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

The citrine gems are beautiful. I appreciated that each stone was individually shown on the website so I could see exactly what I was getting. No mystery person selecting random stones for me. The documentation included with each gem was high quality as well. Great price and arrived as expected.
