I bought my stones and designed my jewelry myself, starting with my stone selection. They are my grandchildren birth stones that I will pass to them later. They are part of me then I will be part of them. Something I created with love for them.

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
