You were the only site that had the color gems with oval cut in sizes 6mm to 4mm that I could find and it was very easy to find them with your search tool!

i made an order in 2007 and was very pleased; it made into a lovely ring. i found a large citrine locally, and now needed some accent stones.

I love the variety of stones available, and especially that I'm not buying from a stock image -- the stone I see online is the actual one I'm getting.

Gem select was a company we were just looking at their products and my wife liked her birthstone so we ordered it and when it came she was very happy with what she received and because of that she wants to order again to make earrings with the next order so Gem Select is the company we will be shopping from now on
