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

I visited several online loose stone shops trying to find rare stones. I finally found one that I've been looking for here, and very satisfied. Looking forward to receive the item in 3 weeks.

I searched for the size, dimensions and quality of the stones I was looking for and then compared and ordered.

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
