Nice inventory, decent pricing. Site is easy to navigate.
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.
i saw a program on the science channel about varieties of fluorite - a special on John 'something' from perhaps wales and varieties of colors... and i was chatting w/ friend who sent me link to your site
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
