: Gem smaller than expected
Frequently Asked Questions (FAQ) / Gem smaller than expected

I recently purchased some gemstones and they were smaller than I expected. Can you help me?

While we can't make your gems larger, we think we know what went wrong. There is a lesson we all have to learn - weight is not the same as size in gemstones! Different gemstone materials have a different density (specific gravity), so some gems will appear larger than others of the same weight. For example, a 1 carat sapphire is smaller than a 1 carat diamond because sapphire is a denser material. We have a weight comparison chart that will allow you to compare the weight of different gemstones in calibrated sizes. We always give the exact dimensions of our gemstones in millimeters on our website, so don't forget to check the size as well as the weight!

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
