I love that I was able to find a site that offers REAL gemstones. I love the pictures provided of the gems so I can look at each one from different angles, I love the variety of gems on the site & I love the ability to narrow down my search to look at certain gems that fit my criteria.

My experience with gemselect was awesome so far. I had a few questions about their website and making orders and they replied quickly and were happy to help. I have not received the items I ordered yet as I just ordered them this morning. Although, I truly feel I am going to be a very happy customer once I do receive my items. Gemselect guarantees all their items and have a great return policy just incase. The have a vast selection of all kinds of stones and not to mention their prices are much better than some other websites. Thanks Gemselect I’ll be doing business here from now on!

Great selection. Love the many learning features like articles and gem information. Prices competitive for natural stones. I do miss not having a selection of lab-made stones, CZ’s, etc, which are useful when price and cost are factors.

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
