Found exactly what I was looking for, but I don't know how to tell the size. I'll have my jeweler nake it fit.

サイズとウェイト

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
