I enjoy doing buisness with GemSelect. It is always a pleasure and you get what you ordered!

I found what I was looking for...had to look up millimeters to inches. It would be nice to see something, like a quarter, in the pix to show relative size. I plan on buy loose gemstones for every month in the calendar

I love Gem Select! When you order what you see is what you get. As soon as you make payment that particular gem is taken off the photo album. That way the one you select is a one of that kind.

Im not a jeweler, I buy for my personal use. My dad was a jewelry maker and I love gemstones.
