Great experience shopping and finding what I was looking for, the only improvement I could think of would be allowing to filter more than one size at a time.

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
