I love GemSelect! Every stone that I ever purchased has been carefully packaged, and sometimes comes with origin info. The stone I just ordered is for my engagement ring, because my Fiance is making my ring! I am so amazed with the selection that this site has, and I am so impressed with the prices.

Site layout was great. Item description was good but this is first purchase so I will have to wait and see how satisfied I am with product. But this step of process was great!

Well I was looking for the perfect stone to set in a ring for my partner. I found this Garnet on a website called Gemselect and it captured my eye. I had to have it for her. It looked as perfect as she does. I got the stone I wanted for $150 shipped straight to me. It’ll be the perfect Christmas present

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
