Gemstones, crystals and precious metals have always been coveted luxurious and expensive objects. Once worshiped for purportedly possessing mysterious powers and now used in jewelry and accessories, their value only rises in the market, making them worthwhile investments for the future.
Each of them have certain properties and are valuable in their own way. But some of them are super rare, found only in specific places and as a result are super expensive.
If you've ever wondered which are the costliest gemstones currently out there, here's a list, ranked in ascending order, with their prices per carat.
The lowest starts off from around a $1000 and it only goes up from there!
10 Tanzanite- $1200 per carat
The majestic blue-violet color of this stone comes from the presence of small amounts of vanadium in it. As the name suggests, this gemstone is found only in Tanzania, in a place near the Mirerani Hills. Interestingly enough, the stone appears blue under a fluorescent light while it takes on a violet tinge under incandescent light.
A Goan tailor by the name of Manuel de Souza had first found this stone and later jewelry company Tiffany and Co, decide to market it and renamed the stone as "Tanzanite".
Owing to its diminishing supply, the price of tanzanite is only expected to go up in the future.
9 Black Opal- $9,500 per carat
Black Opals are the rarest and consequently the most expensive variety of Opal gemstones. The black and grey tones come from the trace presence of carbon and iron oxide in it. The dark background makes for an interesting, vibrant and rainbow-hued play of color on it, making them highly alluring and much sought-after.
They are mostly mined in Lightning Ridge, a region in New South Wales. However although most of the black opals are marketed from there, the gemstone is also found in Southern Australia.
They are usually cut in an oval shape, although free-form and teardrop shapes are also possible.
8 Red Beryl- $10,000 per carat
If you think the prices have just started to skyrocket, you have some big surprises awaiting you!
Red Beryls are the rarest gemstones in the beryl group, in which emeralds also belong. As such, this beautiful dark red stone is often referred to as "red emerald". The red color comes from the trace presence of manganese in the stone.
The stone is mined in the Wah Wah Mountains of Utah and also in Mexico. However, a synthetic form of the stone was manufactured for a while in Russia and later discontinued.
7 Musgravite- $35,000 per carat
This very expensive gemstone was discovered in the Musgrave region in Australia in 1967. And as of 2005, only eight of these gemstones were mined, making it one of the rarest of the rare stones.
The color varies from grey-green to green and looks very similar to another stone- Taafetite. In fact, they look so similar, the only way to tell them apart is by a process called Raman spectroscopy. They are also some of the hardest gemstones.
6 Alexandrite- $70,000 per carat
This gemstone is a special case. All the other ones mentioned on this list are known by their distinctive colors. However, this stone is somewhat of a chameleon in the sense that it can change its color. It's because of this ability, the stone is referred to as emerald by day and ruby by night.
Pretty cool, huh?
This stone was first discovered in 1830 in the Ural Mountains of Russia. It is also found in East Africa, Brazil, and Sri Lanka, although it is exceptionally rare.
5 Emerald- $305,000 per carat
Emeralds are pretty popular and found all over four continents. So why are they so highly priced?
Well that is because most of the emeralds readily available in the market contain some imperfections. As a result, the few rare stones that are completely free of any imperfections are sold at pretty high rates.
The famous Rockefeller Emerald for instance, was auctioned off at Christie's for a whooping $5.5 million. Originally brought by J.D. Rockefeller for his wife, it was sold privately by the family much later.
4 Ruby- $ 1.18 million per carat
Rubies are another highly popular variety and are available in multiple colors from pink to a dark red. The ancient people were attracted to the color and believed the stone represented blood and had mystical properties.
Well it appears that the gemstone still has the world spellbound.
A particular ruby called the "Sunrise Ruby" after a Rumi poem fetched over $30 million at an auction in Geneva. This super rare Burmese ruby was 26 carats, making the per-carat price cross over a million dollars.
3 Pink Diamond - $1.19 million
This one is only slightly more expensive than your average rare ruby. However, when it comes to the world of diamonds, the Pink Diamond is even rarer, comprising only 0.1% of the total lot. Like ordinary diamonds, pink diamonds too can be internally flawless or not.
However, there is only one pink diamond that has been regarded as being completely flawless. It is called the Pink Star and was sold for over $70 million in a Hong Kong auction.
Oh by the way, Pink Diamond is also the name of an anthropomorphic diamond in the Steven Universe show!
2 Jadeite- $3 million
Jadeite, as the name suggests, is one of the gemstones in the Jade family. Available in multiple shades, ranging from red to black, it is the green ones that are most commonly known.
However, the special shade of semi-transparent emerald green, is the one that we are talking about here. Known as "Imperial Jade", this gemstone featured prominently in Chinese culture.
A necklace that contained 27 Jadeite beads was sold to Cartier for a magnificent $27.44 million, making the individual beads super costly.
1 Blue Diamond- $3.93 million
Ah, the crowning jewel of the lot!
A blue diamond has all the properties of other diamonds, in addition to the fact that it is also blue in color. However, their rarity makes them very sought-after in jewelry auctions.
In fact, they are so rare, that the individual Blue diamonds have accrued their own history and folklore. For instance, there's the famous Hope Diamond that is supposedly cursed. Then there"s the famous "Heart of Eternity" that was found in South Africa.
And of course, there's the Oppenheimer Blue Diamond that fetched $58 million in an auction, which holds the record for being the most expensive diamond ever sold.
