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

Would have bought an indigo and selenite, but neither listed. But, you do offer quite a large assortment otherwise.
