The website is very easy to use, easy to find by color, calibrated size, etc. Easy checkout with PayPal (many gem merchants do not accept this payment form). Uses standardized clarity scale, etc.

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
