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.

I ordered peridots online and they were very close to the shade in the photo. They had a good polish and pretty good lapidation for a commercial cut. They had the correct critical angles for the ri of the material so that the stones had life in them. The down side was the lack of tracking and the length of time that it had taken to get them.
