About 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.

I just learned and purchased a “citrine” crystal is hat I found out was a baked amethyst but it can be sold as citrine but it’s not. So I was looking for genuine Brazilian citrine and it brought me to this site, had a ton of selections in various cuts which was impressive and that it comes certified. Which is amazing.

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
