The gem I selected was the right size and matched exactly other gems on the bracelet. This greatly pleased me. The picture and color exactly matched the delivery.

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.

GemSelect is always my first choice for purchasing gemstones. The fact that the gems are always exactly as described and pictured on the website has earned my trust many times over. Even when I don't buy, I still love browsing all the beautiful stones. My new favorites are the bright green Tsavorites!

On the clarity options it goes "and better" so if youre looking for si specifically and you click si and better it still shows you basically everything. It just removes the opaques. Itd be nice if it was vs only, vss only, si only, etc
