Sillimanite
Sillimanite is an aluminum silicate, related to both andalusite and kyanite. In fact these three minerals are polymorphs - they share the same chemical composition but different crystal structures.

Sillimanite is named after the American chemist Benjamin Silliman (1779-1864). Silliman was one of the first American professors of science and taught at Yale University.

Sillimanite gems may show a cat's eye and be cut en cabochon, or they may be faceted, transparent gemstones. The colors of sillimanite include colorless, grayish-white, green, bluish and brownish. A fibrous variety of sillimanite is traded as "fibrolite". Some sillimanite gemstones show pleochroism, which means that several colors may be exhibited in a single gemstone depending on the viewing angle.

Size and Weight

Gems are always measured in Millimeter (mm)

Dimensions are given as;
length x width x depth,
except for round stones which are;
diameter x depth

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size

Note: 1ct = 0.2g
