Currently there are more than six thousand minerals and each year a number of added hundreds of new. Many of them you will never see in life, we use about a hundred of minerals, including precious stones. Minerals can be classified as precious stones, depending on their chemical composition, refraction, crystal structure and optical characteristics. These 12 minerals are the rarest and the most valuable on Earth.
Eremeeva
2000 per carat Eremeeva is a aluminum with attached fluorine molecules. Named after a Russian mineralogist, P. V. Eremeev and first found in Siberia in 1883.
Fire opal
2300 dollars per carat Fire opals — the stones are transparent to translucent, mostly with flowers from hyacinth-red to wine-yellow, sometimes almost red. In Mexico produce variations with opalescence.
Pedretti
3000 $ per carat Poudretteite (Pedretti) is a rare mineral from the group of milarite. Forms a colourless or pale pink crystals. Poudretteite is colorless, light brown and purple-pink. Opened and described in 1986. Despite the extreme rarity of this mineral, it is used as a faceting of a gemstone. The largest cut poudretteite weighs 9,41 CT.
Benitoite
4000 dollars per carat Benitoite is a very rare mineral, a silicate of barium and titanium. Named by the discovery in 1906 in San Benito.
Musgrave
6000 dollars per carat Musgravite is a rare mineral from the group of taaffeite, complex oxides of magnesium and beryllium. The name of Musgrave received on the initial location in Australia, in the valley Musgrave range.
Red beryl
10000 per carat Red beryl is a mineral composed of beryllium, aluminum and silicate. In nature, pure beryl is colorless, but it acquires the color from traces of additional elements. Red beryl is only found in the mountain ranges of Utah, and its cost can reach up to ten thousand dollars per carat.
Alexandrite
12000 dollars per carat Alexandrite is a type of chrysoberyl. Was first found in the Urals in 1830-ies. Has amazing properties to change colors depending on lighting.
Diamond
15000 $ per carat The diamond, cut diamond — pure carbon, sintered in an amazingly beautiful bars. Diamonds used in industry due to its durability. Are found in kimberlite pipes, by the age of 1 to 3 billion years.
Serendibite
18000 dollars per carat Serendibite has a fairly wide range of colors – blue, bluish-green, light yellow, dark blue and an extremely dark blue, almost black. At the present time, reliably confirmed the existence of a little over 1500 cut serendibite, of which are absolutely vast majority are almost black, so dark their tone.
Grandidierite
20000 per carat Grandidieri is a very rare mineral, a silicate of magnesium, iron and aluminum. Color greenish-blue, bluish-green, greenish-blue.
Taaffeite
35000 dollars per carat Tapeit is a unique stone, ohranyaemyi exclusively in Ireland. Precious stone is found in alluvial deposits within Sri Lanka and Tanzania.
Red diamond
1000000 dollars per carat Diamond is expensive, but the red diamond is even more expensive. The red color arises not due to impurities of other minerals, and due to the plastic deformation of the crystal lattice. This makes the mineral more valuable.
