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

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

The site provided lots of detail, factual data, and good photos. I also like the availability of searching by price range as well as by the type of stone.
