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

I love the gems and your website, every time I want to buy I usually spend between 6 and 8 hours on your website.

I have purchased stones from gem select in the past and have been very satisfied. I expect to repeat that experience with this purchase as well

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
