12 Rarest Gemstones in the World
Gemstones in the world are made up of a variety of minerals, rocks, and organic. With more than 300 precious stones currently documented and more than 2000 minerals, there are inevitably some which are much rarer and precious than the diamond, here is the list below. Substitutions of atoms in the crystal lattices, impurities, assemblies, pressure.
Temperature conditions can lead to some of the rarest gemstones in the world. In the list below, we offer a selection of the rarest gemstones. Minerals can be classified as gemstones based on their chemical composition, refraction, crystal structure, and optical characteristics. Today we will tell you about the 12 rarest gemstones in the world.
1: Jeremejevite

The next variety to appear on our list of the ten rarest gemstones is jeremejevite. This colorless gem with sky blue or pale-yellow reflections was first identified in 1883 in Siberia and bears the name of the Russian mineralogist Pavel Jeremejev. Since then, it has only been in Namibia that crystals of sufficient quality have been discovered, but in very limited quantities. Due to the rarity of these crystals, jeremejevite will undoubtedly remain for a long time a highly sought-after collection gemstone. The few copies that exist have incredible value.

2: Fire Opal

Fire Opal (SiO2 · nH2O) is not technically a mineral but rather a mineraloid. The reason for the opal is that it does not have the crystal structure required for all minerals. As stated 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 training. The mineralogy of opal allows it to diffract light, it sparkles in different colors.

3; Poudretteite

Powder is particularly beautiful to look at with its natural pink color, its clarity and its vitreous luster. It comes from a place in the world rich in precious stones: a quarry in Mont-Saint-Hilaire, a small town in Quebec, where more than 60 varieties of gems have been extracted. This quarry is owned and operated by the Poudrette family, Which gave its name to this beautiful variety. The first specimens of powderedite were mined in the 1960s in the form of tiny crystals.

4: Grenat Diamond

Demantoid garnet is a remarkable green variety of andradite garnet that was discovered in the mid-1800s in Russia. Although other types of warm-colored garnet are considered common and inexpensive, demantoid garnet is one of the rarest and most precious of this family. You will be hard pressed to find a demantoid garnet over 2 carats because most of the crystals are smaller. Buying Tip: Demantoid garnet is between 6.5 and 7.5 on the Mohs hardness scale, so the stone is perfect for everyday use with proper care.
Per carat: 2851 €
5: Benitoite

Benitoite (BaTiSi3O9) is a brilliant blue g stone composed of barium, titanium and silica. Benitoïte is formed during the last cooling stage of hydrothermally altered serpentinite. This rare gemstone is found in San Benito County, California, hence its name. The benitoite gives off a strong fluorescence and shines in a bright blue color. Most everyday jewelry lovers will never be able to see the true beauty of benitoite. This stone was discovered in the early 1900s by George D. Louderback. It was the official gemstone of California in 1985.

6: Serendibite

This stone was discovered in 1902 in Sri Lanka by Dunil Palitha Gunasekera. The root of his name is “Serendib” which is the old Sri Lankan name in Arabic. This mineralogical formation results from a highly complex formula with calcium, magnesium, aluminum, silicon, boron, and oxygen which together give it its unique appearance. Cut stones are rare and generally small.
Per carat: 18000$
7: Red Beryl

Red beryl is a mineral composed of beryllium, aluminum and silicate. In nature, pure beryl is colorless but acquires its color from traces of additional elements. Red beryl is found in tuffs of mineralized rhyolite. Red beryl is an extremely rare variety of beryl that has only been found in Utah and New Mexico. It was discovered by Maynard Bixby in 1904. Although it was found in two places, gem-quality red beryl was only extracted in Utah.
Per carat: 8640 €
8: Alexandrite

Alexandrite is a type of chrysoberyl that has been found in the Ural Mountains. The difference between alexandrite and chrysoberyl is the presence of iron, titanium, and chromium present as impurities in alexandrite. Alexandrite is green in the sun and read in the bright light, making it one of the few gemstones that change color on the market. The stone was discovered in 1830 in the Ural Mountains of Russia, which is also home to other unusual minerals.

9: Ruby

Ruby is one of the most popular stones in the world, it is known for its shades of red. Its red color is due to the presence of chromium oxide, it belongs to the corundum family. It can be found on all continents except Antarctica. The main deposits are in Thailand, Myanmar, and Sri Lanka, but the most precious Rubies come from Asia. Sapphires are other variants of corundum. Ruby has a hardness of 9 on the Mohs scale. Diamonds have a hardness of 10.

10: Jadeite

Although seemingly, jadeite ranks at the top of our list as one of the most precious gemstones in the world. This gemstone is the most expensive and beautiful variety of jade. Since this dark green translucent gem is significantly rarer than other types of jade, it is worth much more. Buying tip: If you want jadeite, but you can’t afford the price, consider buying a cheaper version, nephritis or jade dupe, aventurine.

11: Taaffeite

Taaffeite is a very rare mineral often confused with spinel. Surprisingly, the gemstone was first discovered already cut and polished in Dublin, Ireland in 1945. The main difference between spinel and taafeite is the double refraction found in taafeite. The gem is found in alluvial deposits in Sri Lanka and Tanzania. At the time, the gemstone was mislabeled in spinel and after inspection it was determined that the mineral was in reality a new unidentified gem.

12: Red diamond

Diamond is one of the most expensive gemstones in the world, and in number 2 with a price of over $ 1-2 million per carat, we find the red diamond. There are less than 30 red diamonds found worldwide, most of them less than half a carat. You can assume that the red color comes from impurity, but it is actually derived from the plastic deformation of the crystal lattice. There is only one deposit for this stone, it is located in Australia and is called The Argyle Mine.
