When I could not find a good matched pair, Customer Service (Thomas Dahlberg) responded with a selection of beautiful singles, which I also needed, and I found just the right stone for my ring. This means he actually read my email! So unusual these days. So very welcome.

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
