18 Most Rare & Expensive Gemstones

From the most beautiful stones in the world to the most expensive rocks you’ve ever seen these gemstones are worth a shocking amount of money 8. Ruby Rubies come in vibrant shades of dark red, bright red, and purple-red. Like diamonds, they are found globally except for Antarctica. The most valuable of these gemstones come from Asia, and its main exporters are Sri Lanka, Thailand, and Myanmar. The "pigeon's blood" varieties that spot a pure red and violet gue are by far the most popular. A ruby can go for about $15,000 in the world market because of their limited numbers. 7. Rough Diamond The most desirable of all gemstones is a rough diamond, and it also happens to be amongst the most expensive. The wedding industry could be blamed for the enormous popularity of cut diamonds globally. Besides that, most women wouldn't mind adding a jewelry piece carrying diamonds to her collection. Presently, perfectly cut D color diamonds can fetch as much as $15,000 per carat. 6. Serendibite The extremely rare gemstone originally came from Sri Lanka in 1902. The inosilicate features a complex chemical formula and comprises of aluminum, magnesium, calcium, and boron. One of these gemstones recently came out of the Mogok mines in Myanmar. The serendibite goes for $18,000 per carat. 5. Jadeite The Jade's most beautiful and rarest stone just so happens to also be the most expensive. It has been mined in a variety of colors, but its rich-emerald color continues to be the most favored, and these jadeites originate from Myanmar. However, mauve, apple green, and lavender jadeites are also quite popular with buyers. The stone also forms an integral part of the Mesoamerican, Maori, and Chinese cultures where they are used to carve weapons, fashion jewelry, and also used for medicinal and religious purposes. Jadeites are currently priced at about $20,000 per carat. 4. Grandidierite The greenish-blue or yellow-blue mineral is quite rare and was first discovered in Sri Lanka. However, in the twentieth century, Alfred Grandidier, a French explorer, found a bulk of the minerals in Madagascar. Only about two dozen of the faceted grandidierite exist today. The stone borrowed its name from its founder. The unique gemstone goes for $30,000 per carat. 3. Red Diamond Considered the most expensive gem in the world, the red diamond would set you back US$1 million per carat. In the history of mankind, very only 30 samples of these gemstones have been found, and most weigh under 0.5 carats. Australia's Argyle diamond mine is the only place where these diamonds can be mined, and only a few stones are extracted from it each year. While most people might assume that the red color is an impurity, it comes from the deformation of the crystal lattice. The priciest and largest of these stones ever sold was the Moussaieff Red Diamond that went for $8 million in 2011. 2. Blue Diamond Colored diamonds tend to be amongst the most expensive gemstones in the world because of their rarity and spectacular brilliance. Colored diamonds occur in a spectrum of black, yellow, champagne, red, chocolate/brown, pink, green, and blue colors. The most popular are the Pink Star and Oppenheimer Blue. The Oppenheimer Blue diamond has a vivid blue hue and its the largest of such diamonds to go on auction selling for $57.5 million. That particular piece weighed 14.62 carats translating to $3.93 million per carat. The Pink Star recently broke the record selling for a whopping $71.2 million for a 59.6-carat piece. 1. US$3 Million Rare Black Opal Bobby, an Australian miner, found an opal back in 2002. After he fell on hard times, he sold his mining equipment and took home his last bucket of rocks. He began rubbing the grimy stones and discovered hints of gold and green. It took Bobby two years to whittle the encasing rock away from the gemstone hidden inside. What he ended up with was an extremely rare 306-carat black opal. You'd think that he would cash in on the precious stone, but instead, he kept it tucked safely underneath his mattress for another 12 years. It kind of reminds you of a certain character from The Lord Of The Rings, and Bobby himself said that he considered it one of God's greatest creations that he had to guard. He finally entrusted it to Katherine Jetter, an Australian jewelry designer who debuted it at a Wynn Hotel, Las Vegas Couture show for US$3 million. The black opals generally sell at $3,500 per carat. Thanks for watching coming up next Insane Military Tech and Machines That Actually Exist!

Fossil Hunting And Beachcombing At Compton Bay

We wanted to go fossil hunting at Whale Chine, Isle of Wight, but the steps down to the shore have been closed off because of cliff collapse. So we went to Compton Bay instead - and spent a pleasant morning hunting fossils and looking for other things on the beach.

Risk vs. Reward: Cutting a 161 ct Rough Coober Pedy Opal Gemstone

I take a beautiful "problem" opal and somehow manage to get some decent finished opal cabochons out of it. If you just want to see the results, skip to the end! Sorry for the "fast forward" segments! PRICES The rough opal cost in the mid four-figure range in 2014. The finished products (large and small stones) were sold for about 30% more than the rough opal cost. The "scraps" are mine to use as I see fit. CUTTING vs. NOT CUTTING: truly appreciate all of the comments, both positive and negative. I apologize for possibly misleading you guys about the quality of the rough stone.. At the beginning of the video I have photos of all six sides of the rough stone. Five sides of it either have major flaws or lots of sand and potch. Unfortunately, the "good side" is shown TWICE, so it may appear that the high-grade material extended all the way through to the opposite side. That was not the case: From the start of the video, the first 18 seconds are all of the "good side." The true opposite side can be seen at the 41-45 second mark. A number of comments mention that I "wasted a lot of good opal." First of all, I would like to mention that until you have actually held a large, expensive opal, you cannot appreciate the difficulty that you may encounter in cutting it. As many experienced opal cutters know, the yield (percentage of usable opal obtained from rough) for all precious opal ranges from 10 to 50 percent (on average). Some rough may yield as much as 70 percent or more; but because it is easy to detect "high-yield" opal, the seller will price it higher! The stone is the video is severely flawed, by any measure. My yield for this stone was 24.8% (40 carats of 161 carats). The majority of high-grade opal that was truly "wasted" was the opal that was "lost" in making oval, rather than free-form cabochons. For those who know the "loose stone" opal market, oval stones cost roughly 20-25% more than free-form cabochons. I wasted about 7-10 carats of high-grade opal (25% of the total yield; 6% of the 161 ct rough). [The two customers who ordered the pendants actually REQUESTED oval cabochons, and they paid the "oval cabochon" price]. Most of the material that was truly "wasted" was either sandstone matrix, or severely flawed or very potchy opal. Small pockets of high-grade opal that I cut through had to be sacrificed in order to find the main area of high grade material. An additional 10-20 carats of low-grade opal cabochons COULD have been made from this rough, but in my work, I have no demand for low-grade opal. (I personally like the lower grades, but my customers apparently do not!) I try to plan the cutting of an opal as well as possible, but sometimes, the cutting does not go as expected. Even high-yield opal (which this stone was not) usually have unexpected and disappointing flaws. After all of the great opal that I have cut, it is still find it unnerving to start cutting an expensive piece of opal. I should note that although the rough specimen looked nice on one side, it is by no means a "museum specimen." I personally collect opal that is TOO GOOD TO CUT and I DO NOT cut it. This one was NOT in that category. If you would like to see an example of a "TO GOOD TO CUT" stone, please see my video: Thanks for all of your comments and support!

5. Tanzanite
This amazingly beautiful, blue variation of zoisite, a mineral, is found in one area, and a small area it is. Oh, and we forgot to mention that the area in which they are located is at the base of Mount Kilimanjaro! It wasn’t until the 1960’s that the precious stones were found in commercial quantities, so up until then it was a really unknown thing. But, thanks to Tiffany & Co, the popularity of tanzanite has grown substantially. Most tanzanites are heat treated to improve and bring out their blue coloration; however, any un-heat treated, naturally strong blue-colored stones are worth a pretty penny! Someday Tanzanite, like all tanzanite, will probably be worth that pretty penny as well, considering right now it only comes from one location in the world, and once those mines are depleted, there will be no new tanzanite hitting the market. So if you’ve got some now, hold onto it, and pray that it never pops up elsewhere on earth!

4. Painite
Back in 1951, British geologist, Arthur Charles Davy Pain, discovered painite, but it wasn’t until 1957 that it would be officially recognized as a new mineral. When it was confirmed as new, it was named after him, as seems to be the tradition of discovery. It’s made up of aluminum, oxygen, boron, zirconium, and aluminum, and it also contains tiny amounts of vanadium and chromium, which give it its color. It was actually the rarest gemstone in the entire world for a long time considering there was only one known specimen in the entire world, and it was kept in the British Museum in London. Over time, more and more gemstones were found, and by 2004, there were a bunch; however, the number still did not exceed two dozen. In more recent years, mines in Myanmar have produced painite, and the known number of stones is now closer to 1,000, but it’s still really rare. Stones weighing in at just one carat can go for more than $60,000, making it one sought after gemstone.

3. Grandidierite
So, this scarce stone was first found in Madagascar by one Alfred Lacroix, a French mineralogist, who then went on to describe it in 1902, and named it in honor of Alfred Grandidier, a French explorer who was an expert in Madagascan history. It has been found in multiple places throughout the world; however, only stones that have come from Sri Lanka and Madagascar have produced stones that are gem-quality. Most grandidierite are translucent, but the rarer specimens are more transparent, with the most valuable being wholly transparent. The gemstone was actually confused with serendibite, another stone, because grandidierite of that transparency and color had not yet been seen. An expert did an analysis and confirmed that it was, in fact, grandidierite, and the gem was sold for an undisclosed amount of money. Wouldn’t you just love to have a stone you think is one thing and then it turns out to be one even more rare and more valuable? The luck of some people….

2. Red Beryl
This beautiful, rare little gemstone is, in fact, so rare that the Utah Geological Society estimates that just one specimen is uncovered per every 150,000 gem-quality diamonds. It used to go by the name red bixbite and was first marketed as a red emerald. Using the term emerald to sell the beryl today is prohibited considering the red beryl is not an emerald, although the emerald is a variety of beryl. Pure beryl itself is entirely colorless, and the gems only gain color through impurities inside; manganese inside of a beryl will give it a red coloration, creating the red beryl that is found only in Mexico, New Mexico, and Utah. They are typically too small to be cut and used and generally weigh less than a carat. Any red beryl weighing more than two to three carats would be considered an exceptional stone and would be worth quite a bit considering its rarity. It’s not only rare, but it’s beautiful. Too bad we’ll probably never see one in person!
