1.9" Black Andradite (Melanite) Garnet Cluster - Kazakhstan

This is a beautiful andradite garnet cluster of the melanite variety. This melanite cluster was collected from the Sokolovskoe Iron Mines of Kostanay Province, Kazakhstan. The garnets are all deep black in color and display superb luster. There is a small association of pyrite on what could be considered the top this specimen.

Andradite is a species of the Garnet group, and although not as well-known as some other types of Garnets such as Almandine or Pyrope, it is the most lustrous. It tends to be opaque, so most andradite does not make for good gemstones. It occurs in skarns developed in contact metamorphosed impure limestones or calcic igneous rocks; in chlorite schists and serpentinites and in alkalic igneous rocks (typically titaniferous).

Garnets are nesosilicates having the general formula X3Y2(Si O4)3. There are many species of garnet which are pyrope, almandine, spessartine, uvarovite, andradite and grossular (varieties of which are hessonite or cinnamon-stone and tsavorite).

The mineral pyrite or iron pyrite is commonly referred to as Fool's Gold because its metallic luster and pale brass-yellow hue give it a superficial resemblance to gold. In the old mining days, pyrite was sometimes mistaken for gold. Pyrite is the most common of the sulfide minerals with the chemical formula FeS2. Pyrite crystals occur in many shapes and habits. Smaller (druzy) crystal aggregates may give off a beautiful glistening effects, and larger crystals may be perfectly formed, including fascinating cubes, penetration twins, and other interesting crystal forms.
