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.

I visited several online loose stone shops trying to find rare stones. I finally found one that I've been looking for here, and very satisfied. Looking forward to receive the item in 3 weeks.
