For gem web photos - - it would help some inexperienced gem buyers like me to show the gem next to a common object such as a US dime for example. Two of the blue star sapphires I purchased are not suited for ring mounting - - way too small. Now I know to purchase a caret weight of about 12 to 20 carets.

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
