1. Jadeite

At– 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

At– $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

At– $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

At– $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

At– $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

At– $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

At– $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

At– $10,000 per carat. All the members of the beryl family are beryllium aluminum cyclosilicate by chemical composition. Pure beryl is actually colorless; the various colors occur from the presence of impurities, such as chromium and vanadium (emerald), iron (aquamarine, golden beryl) and manganese (morganite, red beryl). White or colorless beryl is known as goshenite.

Red beryl or bixbite was first described in 1904 based on a discovery at Maynard’s Claim in the Thomas Mountains in Western Utah, USA. It was named after Maynard Bixby (1853-1935), an American mineralogist. The name bixbite has now been deprecated by CIBJO, the World Jewellery Confederation, to avoid confusion with another mineral, bixbyite, also named after Maynard Bixby.

Concentrations of red beryl at the initial site were very small and the material was not gem-quality. Facetable material was not discovered until 1958 by Lamar Hodges, who was prospecting for uranium in the Wah Wah Mountains of Beaver County, in Southwestern Utah. Twelve claims were staked: Ruby, 1 through 4; and violet, 1 through 8. The claims were worked as a hobby mine by the Hodges family and by intermittent leases, known as the “Ruby Violet Claims.”

In 1998 a company called Gemstone Mining, Inc. of Utah bought the Ruby Violet Claim for $10 million. The annual yield of red beryl from the mine is only about 5,000 to 7,000 carats a year. GMI is marketing the product as “red emerald,” and touts it as one of the rarest gemstones in the world. Prices run as high as $10,000 per carat for top specimens. Most red beryl specimens are under one carat. A 2 to 3 carat stone would be considered very large.

Some of the red gems being marketed as red beryl or bixbite are actually pezzottaite, a new gemstone variety that was discovered in Madagascar. Pezzottaite is also very rare – but not yet as valuable as bixbite. It is a different mineral altogether, with a different chemical composition, density and refractive index. A new find of pezzottaite in Afghanistan has made this new gemstone more widely available. Red beryl is so rare that it is wise to always insist on certification from a recognized gemological lab when buying this gemstone.

9…Black Opal

BLACK OPAL HAS THE MOST STUNNING COLOURS OF ANY GEM

At over $3,500 per carat.Qld Australia there is a small but famous town called “Lightning Ridge“. This town is the only place on earth that produces this precious Black Opal.

The first recorded Black Opal found in Lightning Ridge was in 1873. However, Until 1903, people were not aware of its value. From that time until now, Lightning Ridge is the only place you can find this magnificent gem, Black Opal. AUSTRALIA

10…Jeremejevite

At $2,000 per carat. Jeremejevite was named for a Russian mineralogist in 1883, but there are rarely any specimens found in Russia today. Recently Namibia has started to produce some mentionable crystals, but in such small amounts the stone is still very rare. Jeremejevite is typically found in pale blue-green, cornflower-blue to yellowish brown hues.
