TOP 10 Rarest and Most Expensive Gemstones Ever. List [1]

NOTE> THERE ARE A NUMBER OF LISTS STATING DIFFERENT GEMS IN THIS LIST. THESE LISTS WILL BE PUBLISHED HERE AS TIME PERMITS SO WE CAN GET AN OVERALL FEEL

[WORK IN PROGRESS]

1. Jadeite

– more than $3 million per carat This gemstone is actually a pyroxene mineral, usually of apple green, emerald green, bluish green or leek green in color. There have also been some that are either greenish white or white with some green spots. Jadeites are colorless in the thin section of the stone. The more intense the green, the more expensive the stone will get. The Chinese, however, also value the white jadeite with green spots. A deep blue-green jadeite that emits a translucent hue has also been discovered in recent times in Guatemala. While it is considered valuable because of historical reasons as the Mesoamerican Olmec used it, the rarity of this specific kind of jadeite has yet to be established. Once the Guatemalans start actively mining for it and confirms its rarity, the value may increase even more.

2. Red Diamonds

– $2 million to 2.5 million per carat This gemstone is very rare. Most of it are actually purplish red, and not crimson or pure red. A mining company located in Australia gets to find only a small number of red diamonds every year. These are then sold at an auction once every couple of years, and you can just imagine the interest, demand and price that the red diamonds command.

3. Serendibite

– $1.8 million to 2 million per carat The serendibite gemstone is an extremely rare mineral that bears boron. Only two areas have been known to produce quality serendibite, namely Ratanapura in Sri Lanka and Mogok in northern Burma. Most of the serendibites found are blue green, grayish blue or pale yellow with a white streak.

4. Blue Garnet

– $1.5 million per carat There are many kinds of garnet in the market. You can find it in a variety of colors, from black, brown, green, orange, pink, purple, red and yellow. There have even been some that do not have any color. But none can compare to the price of the blue garnet. This gemstone was discovered in Madagascar in the 1990s, though it has since been mined in Russia, the United States and Turkey as well. While it has a blue green shade, the generous amount of vanadium in the stone makes it emit a purplish hue when it is held against incandescent lighting.

5.Grandidierite

– $100,000 per carat Alfred Grandidier was a natural historian famed in the archaeology world for his discovery in Madagascar of the skeletons and remains of an elephant bird that weighed half a ton and that has been extinct for thousands of years. He is also famous in the world of gemology for discovering in Sri Lanka a rare stone that transmits blue, green and white light. Initially, they thought it was the gemstone serendibite, but after closer scrutiny, gemologists concluded that it was a totally new stone. It was thereafter named after Grandidier.

6. Painite

– $50,000 – 60,000 per carat Discovered in the 1950s by the Englishman Arthur C. Pain, painite is a rare borate material. It has a natural hexagon shape and has an orange-red or brownish-red color. Trace amounts of iron, vanadium and chromium are present in the stone. While it used to be the rarest stone in the world, more have been unearthed and discovered in Burma recently.

7. Musgravite

– $35,000 per carat This gemstone is actually a silicate mineral that was first discovered in Australia in an area called Musgrave. While similar minerals have since been unearthed in Madagascar, Greenland and Sri Lanka, it is still considered very rare. There are trace amounts of aluminum, berrylium and magnesium present in the stone.  semi precious

8.Bixbite

– $10,000 per carat. [More info to come]

9. Black Opal

$2,355 per carat.[More info to come]

10. Jeremevite

$2,000 per carat. [More info to come]

Ruby sales record at Singapore auction set by Gemfields

The miner is currently a takeover target from Chinese and South African interests.

At the auction, held in Singapore, the company sold $54.8 million worth of rubies, a record high for any Gemfields auction and a 24% increase in revenue from the previous record.

Of the 83 lots offered, 78 were sold with an average realized price of $61.13 per carat, the miner said. Al the stones offered were extracted by Gemfields’ 75%-owned Montepuez Ruby Mining at the deposit of the same name in Mozambique.

Since June 2004, the gems producer has held eight auctions for precious stones mined at the Montepuez deposit.

Gemfields, which owns the luxury Fabergé jewellery brand, is the world’s biggest coloured gems producer, accounting for approximately a third of the world’s emeralds and rubies from two African mines in Mozambique and Zambia.

Gemfields fetches $29 million in Singapore rubies auction

Rubies from Montepuez, located at a geologically critical junction between the north-south trending Mozambique Belt and the east-west trending Zambezi Belt.

Shares in Gemfields (LON:GEM) climbed Monday as the precious stones miner said it generated sales worth almost $29 million from its latest ruby auction held in Singapore, with prices meeting expectations.

The company’s stock was up 3.4% to 40.84 pence in mid-afternoon trading in London. However, Gemfields value has dropped about 12% so far this year as the diamond and other precious stones industry has not remained immune to a relentless rout in commodity prices.

Gemfields managed to sell 90,642 carats of the 92,136 carats it made available under the auction

Gemfields managed to sell 90,642 carats of the 92,136 carats it made available under the auction, which consisted of a mix of higher and medium quality stones from its relatively newly acquired Montepuez deposit in Mozambique.

The event was third auction held by the company in the current financial year, which ends in June 2016. The first two were either comprised of higher-quality emerald or lower-quality emerald and beryl from its other Kagem mine, making it hard to compare the results, said the company.

Until recently, Gemfields was synonymous with emeralds. But the world’s biggest producer of the green gemstone has done quite well with Montepuez. A cache of exceptional-quality rubies from this mine have made their way onto jewels by the likes of Fabergé, Georg Jensen and Miiori – modelled by brand ambassador actress Mila Kunis.

The miner has said it expects trading in gemstones to account for a “sizeable chunk” of its revenue over the next five to 10 years.

The next auction, to be held in March, will be of predominantly higher quality emeralds from its Kagem emerald mine in Zambia.
