Uvarovite is a calcium chromium with the formula Ca 3 Cr 2 SiO 4 3. This is a rather rare, bright green in color, usually found as small crystals associated with chromite in peridotite, serpentinite, and kimberlites. It is found in crystalline marbles and schists in the Ural mountains of Russia and Outokumpu, Finland.
Garnet is not a single mineral, but describes a group of several closely related minerals. Pyrope, Almandine, Spessartite, Uvarovite, Grossular, and Andradite. All species ofs possess similar physical properties and crystal forms, but differ inposition.

Associated minerals are useful as well, especially the presence of the polymorphs of staurolite, which occur frequently with kyanite. However, the most useful characteristic in identifying kyanite is its anisotropism. If one suspects a specimen to be kyanite, verifying that it has two distinctly different hardness on perpendicular axes is a key to identification it has a hardness of 5.5
The Mineral Group is not a single mineral, but a group contains closely related, isomorphous minerals that form a series with each other. The members form intermediary minerals between each member, and may even intergrow within a single crystal.
