Everything was good about this order except I was a little disappointed in the product because it was so small. This is the first time that I have ever bought a gem so I was very unfamiliar with the sizes mainly because measurements were in metric.

This business makes it easy to research and find all pertinent information about the individual gemstones and other information such as the recommend use (ring or pendent for example). Also it's important to know about things like hardness and durability of the gemstones. I also appreciate the history of purchases and transaction details. Just be sure to register on the website to get the best experience.

I like to use GemSelect for finding calibrated sizes of gemstones. I purchased sapphires a few years ago and found the quality to be outstanding so I went ahead and purchased some more today (different) and some really unique moonstone. I'm opening a jewelry busy soon and so accurate gemstone sizes, quality, and reliability as a supplier is really important to me. Gemselect seems to fill all those requirements.

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
