Gemselect is o.k the prices are pretty good, but the shipping prices really suck, one time I order from them and order got lost or never came, but they were good about fixing the problem and rectifying the situation, the stones and good, and the ones that come in the mail, look just as pictured on the website, or all it's not bad and its were I go to get my stones.

It was super easy to browse all the gemstones and find exactly what you wanted. The prices were great and the checkout process was smooth. Seems like a great site, will definitely come back to find more in the future.

Ive always been pleased with quality and truth of gems rating I am a gemmologist and really like the descriptions as well . i.e cut, colour and quality Sometimes Ill choose GemSelect rather than a local wholesaler because of my regard for their quality and truth

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
