About Cat's Eye 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.

I just bought this beautiful pink opal and strawberry quartz from Gem select. I was pleasantly surprised that they had little print outs with all the details and color pictures of the actual stones! If you have been thinking of buying gemstones I highly recommend checking out Gem Select! They have great selection and variety! Top notch!

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
