I did not realize these stones were of jewelry quality. They are really beautiful, just not what I was expecting which was more of a natural stone.

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
