The fact that there are no stock photos is very impressive. Shows the detail and professionalism of the company. There are thousands of gems and it’s very organized. I was able to find exactly what I’ve been looking for.

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
