I was really looking for a gem quality jadeite, exactly 7mm round. No such luck anywhere, so I bought several other 7mm stones just to look. Was fun rummaging through all the goodies.

Great selection of items easey to place order definitely will order from you again Just wish that there was a place on the sight to convert MM to inches or be able to pick between mm and inches to determine the size of stone's for those of us that do not use the metric system

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
