Gem select is the most trustworthy web site for gems. What I see in the picture is exactly what I get. Size is indicated by carat weight, and not the picture size, as they are trying to give an up close view of the gem I am hoping to buy. It was so easy to find the stones I was looking for at a price I could afford.

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
