They have a wonderful selection of gems of all sorts, shapes, cuts, and quality. I am very particular about the quality of stones I buy, and found many with VVS clarity and excellent cut and polish. I am thrilled with each of the stones I purchased, and would definitely recommend GemSelect to everyone.

The citrine gems are beautiful. I appreciated that each stone was individually shown on the website so I could see exactly what I was getting. No mystery person selecting random stones for me. The documentation included with each gem was high quality as well. Great price and arrived as expected.

Site worked well and helped me find a rock that matched what I was looking for. Well within budget and I trust it will show up, so that's definitely positive. Not much else to it. Satisfied.

My experience has always been fantastic. Today I saved 6 gems to email a customer looking for a particular color blend to fit into an east west setting, so her options were limited, but we found one she wanted, deleted all the others in the cart and order the gem she selected. It was helpful to be able to put them in the cart so I could save them until she selected the one she wanted without having to research all of them again.
