Thousands of tradespeople commute from Perth by plane, working 12-hour shifts on 24-hour-a-day mining operations. Even the newest qualified earn well over $100,000 a year, but the money has consequences: In towns near mines, prices for everything from property to services are high. Al Jazeera's Andrew Thomas reports from Western Australia.

10 Most Valuable Gemstones Ever Found

Note: just because it’s found on earth, doesn’t mean it’s from it! 10. Tanzanite 9. Grandiderite 8. Black Opal 7. Taaffeite 6. Alexandrite 5. Musgravite 4. Painite 3. Serendibite 2. Red Diamonds, Pink Star Diamond 1. Jadeite Poudretteite This mineral was first found during the mid-1960’s in the Poudrette quarry of Mont Saint-Hilaire, Quebec. However, it wasn’t until 1987 that the poudretteite was fully recognized as a new mineral. Even then, this mineral wasn't described in depth until 2003. As stated by several different sources, it’s believed that only a relative few will ever come into contact with this mineral and let alone ever even hear it mentioned. Grandidierite This is considered to be an extremely rare mineral and gem that was first seen in 1902 on the Island of Madagascar. It was named in honor after the French explorer Alfred Grandidier who once studied the island’s natural history. Grandidierite comes in a bluish-green color and is located almost entirely in Madagascar, although, there was a clean faceted sample that was found in Sri Lanka. Grandidierite is also pleochroic, which means it's able to absorb different wavelengths of light differently and that results in different colors, such is the same ability with the gems tanzanite and alexandrite. Painite This gemstone was first discovered back in the 1950’s in Myanmar by a British mineralogist named Arthur C. D. Pain. For the next several decades only two fragments of the hexagonal mineral were known to exist on earth. By the time the year 2005 rolled around, there were still less than 25 discovered pieces of painite and The Guinness Book of World Records had declared it the world's rarest gemstone mineral. However, that was 11 years ago and since then the origin of the original stones has been found, along with two other major locations that have led to the discovery of thousands of small samples of painite fragments. Even so, they’re still considered one of the world’s rarest minerals. Ammolite This rare gemstone can be found mainly in the eastern region of the Rocky Mountains of North America. Ammolite is an opal-like gemstone that is solely made up of the fossilized shells of extinct animals known as ammonites. This makes ammolite one of the few biogenic gemstones that exist, along with pearls and amber. Ammolites weren’t officially recognized as gemstones until 1981 when they were given official status by the World Jewellery Confederation. That’s also the same year that commercial mining for ammolite began. Tanzanite It’s been said that tanzanite is 1,000 times rarer than a diamond, which might as well be the case considering the fact that it can be found almost entirely near the foothills of Mount Kilimanjaro. This is where the perfect conditions lie in order to form the mineral. Like grandidierite, tanzanite is able to produce striking shifts in color based on the crystal’s orientation and the certain lighting conditions. Caltech's geology division states this is because the color variations are caused by the existence of vanadium ions. Red Diamonds Did you know that diamonds come in a variety of colors? In fact, diamonds can range from being yellow, brown, colorless, blue, green, black, pink, orange, and red. That’s also the same order of how rare each diamond is classified as with yellow being the least and red being the most. Not only that but diamonds are also the hardest natural substances that form here on earth. Just like the colorless diamond, the red diamond is made purely out of carbon, however, what gives the diamond its red color is actually a deformation of their atomic structure that’s known as a “plastic deformation”. The Moussaieff Red is the largest red diamond in the world among the little known other red diamonds that have been discovered.

Rainbow Opals - Hidden Treasure (Full Documentary)
 
25:31
Our world produces some incredible rocks. Take the opal, a precious stone that forms out of silica, in the dark under the surface of the earth. When cut and polished, it flashes with a gorgeous array of colours, from pale milky hues to deep reds and blacks. Now, an opal that has been named the finest ever unearthed will be making its public debut next month as the centrepiece of an exhibition opening at the South Australian Museum, Adelaide. Called the Virgin Rainbow, it was discovered in the opal fields of Coober Pedy by opal miner John Dunstan in 2003. It's actually an opalised fossil, from an extinct cephalopod called belemnitida that existed during the Mesozoic era. During that time, much of South Australia was under a vast inland sea filled with prehistoric aquatic reptiles called plesiosaurs. These died and sank to the bottom of the sea, buried over the millennia by sediment. When the sea dried up and the land turned into a desert, the acidity levels in the shallow top layer of the sandstone increased. This released silica from weathering sandstone into the layer of clay beneath, where bones and pockets left by disintegrated bones lay buried, carried down via groundwater. Further weathering lowered the acidity levels, which allowed the silica gel to harden into opals in the pockets and impressions left by decayed animal material, like cake poured into a mould, or to soak into bones and create a replica of the internal structure. The famous Australian opal fields of Coober Pedy are located in this region. No other environment in the world is known to have undergone this same process, which is possibly why over 90 percent of the world's opals come from South Australia. SUBSCRIBE

South Australia: From Oceans to Outback
 
23:48
http://www.wanderlust.co.uk/ExploreAustralia From the rugged Outback to the glittering Southern Ocean, South Australia is known for its wildlife, food, wine and beauty. South Australia is vast, spanning nearly half a million square miles. With a population of around one point six million people, that’s just four people per square mile. Kangaroo Island is Australia’s third largest, and home to a remarkable range of wildlife. With over 800 native species of plants and rare sights like the endangered glossy black cockatoo, Kangaroo Island is typified by unspoiled wilderness and a magnificent selection of flora and fauna, including the kangaroos that give it its name. Just over a thousand sea lions live and breed in the Seal Bay Conservation Park, one of the most popular tourist attractions of Kangaroo Island. Marine life thrives all across the shores of South Australia. The state’s coastline stretches for more than 3,000 miles, and after a flight of just 40 minutes from Adelaide the mighty Eyre Peninsula awaits. Baird Bay is a small fishing village situated on the west of the peninsula. Snorkelling here isn’t a typical experience, as the the coastal waters are home to Australian sea lions and pods of dolphins. Adelaide, the state capital city, was founded in 1836 as a planned, freely settled colony. It was a place where immigrants could settle free from religious persecution. Nowadays the city remains a vibrant, bustling cultural centre, home to thriving markets, a lively night scene and dozens of festivals a year. From Adelaide’s beautiful architecture to a wealth of museums detailing its immigrant settlers, Adelaide does not shy away from its multicultural history. For example, the South Australian Museum houses the largest collection of Aboriginal ethnographic material in the world. Climbing away from the coast and the bustle of the city are the quiet, rural hills of the Barossa Valley. The Barossa is world-renowned for its red wine, and over 150 wineries lie within an hour’s drive from Adelaide. But the Barossa is not only home to wine. It’s one of the world’s top culinary destinations. The vibrancy of South Australia doesn’t end in Barossa. Follow the Stuart Highway north, beyond the hills and the vineyards of the Clare Valley to where green turns to red and the Outback begins. For many the jewel in the crown of this region is the dramatic stretch of rock known fondly as the ‘Organ Pipes’. Gawler Range. Enormous, solid volcanic rhyolite is stacked in the cliff face here, ranging in size from stony grinning teeth to the elongated pillars that remind so many people of magnificent organs. The rugged landscape of the Flinders Ranges epitomises the romanticism of outback Australia: big skies, incredible sunsets, and sun-baked desert as far as the eye can see. In the summer it’s a hot, dry landscape. It might seem daunting at first, but look a bit closer and you’ll find the place teeming with life. The Flinders Ranges have also been inhabited by humans for thousands of years. Aborigines have walked in these hills since long before European settlers arrived, using the plants and the rocks for food and creating art. The Flinders Ranges are now home to numerous towns and villages scattered along the highway. The area is accessible as a destination for hiking, cycling, camping and wildlife watching, giving visitors a taste of the iconic outback. Rawnsley Park Station is a working farm that has managed to find a way to blend sheep farming and tourism. The owners provide scenic flights over the spectacular geological formation, Wilpena Pound. Wilpena Pound is an ancient valley floor amidst mountains that have been eroded over hundreds of millions of years. Its golden walls are formed of highly resistant quartzite and sandstone. The area is protected from mining and most human impact other than tourism. Nowadays, 4x4s can be seen roaming along the ridgetops that command spectacular views of the timeless landscape. Life can nevertheless be found all over the northern reaches of South Australia. The emu is a large, flightless bird, endemic to Australia and a close relation of the ostrich. Its long legs allow it to reach speeds of up to 30 miles an hour. It has become an iconic image of Australia. Continuing up the spine of the country, we reach the northern regions of South Australia. This is opal mining country, and the Painted Desert may seem barren, but can be extremely lucrative for those willing to work. The town of Coober Pedy is the opal mining capital of the world, known for the way its people live underground in dugouts to escape the fierce desert heat. We’ve travelled from the crystal waters of the Southern Ocean to the dry beauty of the outback, covering one of the most magnificent states in Australia. The Explorers’ Way crosses the state border, slicing the country in half as it continues into the Northern Territory.

The Cullinan Diamond (530 Carats) The Cullinan Diamond was discovered in Gauteng, South Africa, in 1905. The large blue-white stone was just 30 feet from the surface and was extracted by a miner with a pocket knife. Easy peasy!! He took it to the office to have it measured, and it weighed 3,106.75 carats, about 621 grams, which made it by far the largest diamond to have been found at the time. 9. The Golden Jubilee (545.67 Carats) Weighing in at 545.67 carats, the Golden Jubilee diamond is the largest cut and faceted diamond in the world. From images, it looks to be a golden orange color, but it's actually graded as a fancy yellow-brown stone. 8. Star of Adam (1,404 Carats) In 2016, the world’s largest blue sapphire was unearthed in Sri Lanka, weighing in at a massive 1,404 Carats- which is the equivalent to almost 10 ounces. It came from a mine in the southern city of Ratnapura- a place that is known as the “city of gems” because of the large numbers of precious stones that are found there. Still, this was a major find- the Sri Lankan gem industry is thought to be worth about 103 million dollars annually, but this one was valued at more than 100 million dollars just by itself!! 7. The Rajaratna Ruby (2,475 Carats) The Rajaratna ruby was first unveiled in 1986 and, at the time, was thought to be the largest ruby in the world. It's had an eventful history, and was thought to have originated in either one of India's two well-known ruby and sapphire regions during medieval times- Kalinga and Kalpur… or Mogok in Burma- places synonymous with discoveries of large gems. 6. The Pearl of Puerto (75 lb) In 2016 the world’s largest pearl was found in the Philippines in the most unlikely of places- underneath a fisherman’s bed, where it had been for at least 10 years. According to the man, he had found it while out fishing when his boat’s anchor had become tangled with a giant clam, and he had to swim down to dislodge it. The pearl is one foot wide, 2.2 feet long, and weighs 75 pounds- which means it could be worth as much as 100 million dollars! 5. Sergio Diamond (3,167 Carats) While it’s not worth as much as other diamonds that have been found, the Sergio Diamond is something quite special- and is thought to have been the largest rough diamond to have ever been discovered. 4. Olympic Australis (17,000 Carats) Australia is undoubtedly the home of opals, and in 1956, at the ‘eight-mile' mining field in the town of Coober Pedy, miners found the largest ever to be discovered. It was dug from a cavity about 30 feet beneath the surface, and they couldn't believe their eyes when they realized what it was. Weighing a massive 17,000 carats, it's 11 inches long and 4.5 inches high. 3. 125West Ruby (18,696 Carats) Rubies are a type of corundum mineral- given their name because of their deep, rich, red hue. They come in a variety of colors, though, with red ones always being called a ruby, and other types being called sapphires. They are the second hardest known minerals, after diamonds, so great care has to be taken when turning rough stones into polished pieces. 2. The American Golden Topaz (22,892 Carats) Topaz is well known for its ability to form huge crystals, but the even the miners of Minas Gerais in Brazil were surprised in the early '80s when they dug up some particularly amazing stones. 1. The Bahia Emerald (1.7m Carats) And of course no list of giant stones would be complete without this big guy! This is the biggest rough gemstone that has ever been found- the Bahia Emerald. It was found in a mine in Bahia, Brazil, in 2001, and is a rock that contains 9 crystals- one of which is the largest single emerald crystal to have ever been discovered. In total, the Bahia rock is thought to contain at least 1.7 million carats, and is estimated to be worth up to 400 million dollars.

The Town that Lives Underground
 
04:06
Coober Pedy in South Australia is a town almost completely built underground. It is located 526 miles or 846 km north of Adelaide on the Stuart Highway. A 2011 census found there was a population of 1695 people living there. The name Coober Pedy comes from a local Aboriginal term kupa-piti which means boys waterhole. This town is referred to as the opal capital of the world because of the incredible opals that are pulled from the mine near town. Most people live in below ground houses called dugouts which dramatically help with the scorching daytime heat. A standard 3 bedroom house costs about the same to build than an above ground home. Below ground homes remain at a steady temperature where above ground homes need air conditioning to survive the hot Australian heat. Temperatures in summer time can go above 104 degrees F or 40 degrees celsius. The first houses in Coober Pedy were holes dug in search for opals, once an area was cleared of any opals it became someone’s tiny house. Today opal mining isn’t allowed within town limits but you can always add another room to your house which isn’t considered mining. Back in the old days all the underground homes were built with picks and shovels but today only modern machinery is used and does the job significantly faster. When a tunneling machine finishes a room an attractive pattern is left on the walls and ceiling which is then finished off with a clear sealer to prevent dust. The town relies on tourism and the opal mine for most of the employment. The first opal found in Coober Pedy was on February 1st 1915, today Coober Pedy features over 70 opal fields making it the largest opal mining area of the world. The opals sell at wholesale auction for around $50 - $200 per thumb sized opal. Nothing like $100 dollar bills in the walls of your house. The mine is a popular tourist attraction but the town also has people visit the graveyard and the 2 underground churches. There are more than 1 motels that offer underground accommodation ranging from a single room to than entire motel being underground. The one and only tree within the town is welded from scrap pieces of iron which sits on a hilltop overlooking the town. Surprisingly there is a golf course in town which is completely void of grass and played at night time with golf balls that glow in the dark. Golfers will take a patch of turf around with them for the tee off at each hole. The Coober Pedy golf club is the only one in the world to have reciprocal rights at world famous St. Andrews club. The town also has a Australian football club that must travel 560 miles or 900 km just to play their matches at Roxby Downs. Coober Pedy is a very isolated place, temperatures can swing from scorching hot during the day to almost freezing at night. https://en.wikipedia.org/wiki/Coober_Pedy Music: Jon Wilhelmi https://soundcloud.com/jonathanwilhelmi/ambient-mix Check out some of our other videos: Top 10 Fruits You’ve Never Heard Of Part 2 https://www.youtube.com/watch?v=hRdgPyZF45g&feature=youtu.be Top 10 Fruits You’ve Never Heard Of https://www.youtube.com/watch?v=OKTej1u-7-0&feature=youtu.be Top 5 Most EXTREME Roller Coasters https://www.youtube.com/watch?v=sTofF4_OPkM&feature=youtu.be Top 10 Craziest Lego Creations – Lego Sculptures to Blow Your Mind! https://www.youtube.com/watch?v=mip9G0_rUTk&feature=youtu.be Top 10 LONGEST LIVING Creatures on Earth https://www.youtube.com/watch?v=IDaPH_ZGiVw&feature=youtu.be Support TTL by using our amazon link: http://amzn.to/2dQQ4nu Subscribe to our channel! → http://bit.ly/subscribe_to_titantoplist For copyright matters please contact: [email protected] Check us out on social media: Website - http://www.titantoplist.com Facebook - https://facebook.com/titantoplist Twitter - https://twitter.com/titantoplist Instagram - https://www.instagram.com/titantoplist Here at Titan Top List you'll experience the world's best mysteries, science, facts, news, conspiracies, inventions, scams, movies, games and amazing animals.

Opals
 
03:14
Opals are Gem Stones! Technically, this mineral is made of silica, the chemical name for silicon dioxide. Common forms of silica are ordinary glass and crystals of quartz. The opal mined today was formed many millions of years ago in volcanic rocks. Opals formed when silica, carried by water, deposited in voids left by gas bubbles and in rock fractures. The silica did not crystallize, but solidified from a gel to form microscopic spheres. Water was trapped in these spheres so light passing through the water is broken into the spectrum of colors seen in this precious gem. The effect is similar to light passing through water drops in the sky to form a rainbow. If you have an opal, you possess your own rainbow! One of the best areas to view and buy opals is in the town of Magdalena, in the state of Jalisco, a one-hour drive north west of Guadalajara. Take the auto pista ( Cuota) to Tepic and leave at the Magdalena exit. Alternatively, use the old highway to Tepic, which is in good condition. Magdalena is just 20 minutes from the distilling town of Tequila so the area has more than one attaction. . It takes around five million years for about a centimetre (a little more than a third of an inch) of opal to develop. Australia produces around 95% of the worlds opals. The majority of this Opal is white Opal from the fields of Coober Pedy in South Australia. Few gemstones evoke the excitement of a precious Mexican fire opal. The flashy show of this gem makes each specimen unique, a fountain of mystery, enchantment and legend. Some say that opals convey foresight and good health. No wonder that it is the October birth stone. Pre-historically, the Aztecs are said to have decorated their most prized artworks and figurines with inlaid fire opal. Today precious opals produced from Mexican mines are sought after in the U.S.A., Canada, Europe and the Orient. When these radiant stones are enhanced by a gold mounting, the results are spectacular. Working with native material, Mexican jewelers create beautiful yet modestly priced treasures of opal jewelry. Indeed, the value of jewelry exported from Mexico in the first half of 1999 was estimated at just over 100 million dollars.

12 Rare and Most Expensive Gemstones In The World
 
10:01
Watch 12 Most Expensive Gemstones In The World 12. Jeremejevite Jeremejevite is an aluminum bearing borate mineral with associated fluoride and hydroxide. It was first found in the Adun-Chilon Mountains in Siberia in 1883. This gem has a similar hardness as quartz, 6.5 to 7.5 on the Mohs scale, and therefore is ideal for jewelry making. The Jeremejevite goes for about $2,000 per carat 11. Fire Opal Fire Opal is actually not technically a mineral but instead is a mineraloid. The reason being opal does not have a crystal structure that is required for all minerals. As noted in the chemical formula, opal is a hydrated form of silica or silicon dioxide. Opals can form in a variety of different colors depending on the environmental conditions during formation. The Fire Opal goes for about $2,300 per carat 10. Taaffeite Taaffeite is not very familiar to many due to how rare it is. In fact, it is so scarce that it’s considered to be a million times rarer than a diamond. It was discovered by gemologist Richard Taaffe in 1945 in a jeweler’s shop in Dublin, Ireland. The light violet, almost clear gemstone is the only one that has been initially identified from a faceted stone. The Taaffeite goes for about $2,500 per carat 9. Demantoid Garnet Demantoid is a green gemstone that has a “diamond-like” adamantine luster. Fascinatingly, its brilliance and dispersion actually exceed that of a diamond’s. It is also difficult to look for a demantoid larger than 10 carats as these stones are typically small in size. With the low supply, they are only usually seen on antique jewelry pieces. The Demantoid Garnet goes for about $3,300 per carat 8. Black Opal Opal gemstones have a different evaluation process than other gemstones with each one of them having their own distinct individuality. Compared to other opals, black (with body tones from N1 to N4) are considered rarest and most popular. Its body has a black color with a firey pattern that looks spectacular in contrast to the dark background. The Black Opal goes for about $3,500 per carat 7. Benitoite Considered as one of the most beautiful gems, Benitoite has a striking blue body color that has a dispersion higher than a diamond. As its name, it was discovered by the headwaters in San Benito River in San Benito County, California where it’s now declared as its state gem. While it has a high dispersion, its intense blue color can mask it. The Benitoite goes for about $3,800 per carat 6. Padparadscha Sapphire Padparadscha (pronounced pad-pah-raj-ah) sapphire, the world’s rarest sapphire, has a beautiful pinkish orange color that exhibits the mixture of the hues of ruby and yellow sapphire. Its name is derived from the Sanskrit/Singhalese word for “aquatic lotus blossom” due to its color. The Padparadscha Sapphire goes for about $8000 per carat 5. Red Beryl Red beryl (also known as bixbite, “scarlet emerald” and “red emerald) is an extremely rare type of beryl with a raspberry pink to almost purplish red color. Despite its name, it is not an emerald but it’s an entirely different gemstone. It was first discovered in 1904 by Maynard Bixby. Meanwhile, its gem quality stones can only be found in one site – the Wah Wah Mountains in Utah. The Red Beryl goes for about $10,000 per carat 4. Alexandrite Alexandrite is a very rare (and very hard to acquire) gemstone variety. It is popular for its remarkable optical properties: it undergoes dramatic color shifts depending on the lighting condition. This is caused by the rare combination of minerals including chromium, iron, and titanium. The Alexandrite goes for about $12,000 per carat 3. Jadeite Jadeite is jade’s most expensive, beautiful, and rarest variety. While it can be found in many colors, its association with the rich-emerald color of “imperial jade” continues to be highly valued. The finest stones in this color can be found in Myanmar. The Jadeite goes for about $20,000 per carat 2. Musgravite Nearing the top of the list is Musgravite, an extremely rare gemstone in the taaffeite family. The mineral was first discovered at the Musgrave Range (thus its name) in South Australia. It has shown up in other areas such as Antarctica, Greenland, and Madagascar but in highly limited quantities. As of 2005, there are only 8 known specimens of this stone to exist. The Musgravite goes for about $35,000 per carat 1. Blue Diamond Two of the most stunning examples are the Oppenheimer Blue and the Pink Star. The Oppenheimer Blue diamond is the largest Vivid Blue diamond to appear at an auction and was sold $57.5 million for weighing 14.62-carats which makes it worth $3.93 million per carat. Meanwhile, the recent world record breaker, the Pink Star diamond, was sold at a whopping $71.2 million for 59.6-carats (or $1.2 million per carat) becoming the most expensive gemstone ever sold based on its total price. #Expensivediamonds #Gemstones #Pinkstardiamond

A Brief History of the Royal Peacock Opal Mine
 
04:21
A brief history of the Royal Peacock Opal Mine. www.royalpeacock.com It took fourteen million years for Mother Nature to make a Virgin Valley opal. It was well worth the wait. More than a quarter of a million carats of precious fire opals have been extracted from the Royal Peacock mines in the past twenty five years. The most spectacular black opals in the world come from the Royal Peacock mines in Virgin Valley, Nevada. Virgin Valley opals are found in layers of clay that were formed when volcanic ash filled an ancient lake millions of years ago. The surrounding forests were also choked with the ash. The lake had twigs and limbs and rotting wood collected in its coves. The buried wood decayed and left lifelike cavities as mementos of their presence. Heat and pressure formed a silica gel that percolated through the ash and filled the cavities. It gradually hardened into opal. In a small percentage of the opals the cells aligned to create opals with a fiery soul -- precious black opals -- the most beautiful gemstones in the known universe. Of course, not all Virgin Valley opals are "black." We also produce moss opal, lemon opal, crystal opal, and white opal. Additionally, we are the only known source for fluorescent opal, which fluoresces green when illuminated with black light. Virgin Valley opals are usually found in pockets. When you find one there are usually others nearby. This reinforces the current theory that most of the limbs were floating in an ancient lake, and crowded together in small coves and back eddies.

Meet the Virgin Rainbow, the most beautiful opal in the world
 
02:33
An opal so fine it has been valued at over $1 million is about to go on public display for the first time. Our world produces some incredible rocks. Take the opal, a precious stone that forms out of silica, in the dark under the surface of the earth. When cut and polished, it flashes with a gorgeous array of colours, from pale milky hues to deep reds and blacks. Now, an opal that has been named the finest ever unearthed will be making its public debut next month as the centrepiece of an exhibition opening at the South Australian Museum, Adelaide. Called the Virgin Rainbow, it was discovered in the opal fields of Coober Pedy by opal miner John Dunstan in 2003. It's actually an opalised fossil, from an extinct cephalopod called belemnitida that existed during the Mesozoic era. During that time, much of South Australia was under a vast inland sea filled with prehistoric aquatic reptiles called plesiosaurs. These died and sank to the bottom of the sea, buried over the millennia by sediment. When the sea dried up and the land turned into a desert, the acidity levels in the shallow top layer of the sandstone increased. This released silica from weathering sandstone into the layer of clay beneath, where bones and pockets left by disintegrated bones lay buried, carried down via groundwater. Further weathering lowered the acidity levels, which allowed the silica gel to harden into opals in the pockets and impressions left by decayed animal material, like cake poured into a mould, or to soak into bones and create a replica of the internal structure. The famous Australian opal fields of Coober Pedy are located in this region. No other environment in the world is known to have undergone this same process, which is possibly why over 90 percent of the world's opals come from South Australia.
