Finding the right gemstones was easy on the web page. Payment was quite simple as well. Design of the site was nice and simple; however, the "Create Your Gemstone Lots" image appears fuzzy and lowers aesthetics in my opinion.

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
