A rare and very beautiful Andesine Labradorite earth mined in the Ukraine.
Andesine is a member of the group of minerals known as Feldspars. In the gemstone world, Moonstone is another famous Feldspar. But Moonstone is an Orthoclase Feldspar while Andesine is one of the Plagioclase Feldspars, which include Oligoclase, Andesine, Labradorite and Bytownite.
Confusing ? Just a little !!
All the members of the Plagioclase Group are a mixture of Albite and Anorthite, with Andesine being 50-70% Albite (sodium aluminum silicate) and 30-50% Anorthite (calcium aluminum silicate). Labradorite is defined as between 50-70% Anorthite and 30-50% Alibite, so many specimens of similar appearance may fall into one category or the other.
Andesine occurs in a range of colors, from red or honey-red to orange, yellow, champagne or green. It has a hardness of 6 to 6.5 on the Mohs Scale. It is translucent to transparent and has perfect cleavage.
