I have been ordering from GemSelect for at least 6 years. Every single order was perfect - every item was as advertized, in perfect condition and arrived well within the specified time frame. I have recommended them to several friends.

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
