Easy picking, fast checkout, secure shipping. Cana't ask for anything more than efficiency and a good price.

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.

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