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.

Have made 2 purchases so far from GemSelect and they have been amazing! Anytime I requested additional info, videos or pictures of a particular item, the response was always timely and helpful. This is a great place to buy, if you are looking for loose stones. Highly recommend!

I needed a very specific color of tourmaline and Gem Select had it. I had to get the client to agree and then ordered the stone. It arrived better than pictured and we all were very happy.

All items were delivered on time with all items meeting or exceeding my expectations. Cut, clarity and color were very close to the photos and description.
