I like the site, it's easy to navigate. There are sometimes items I'm looking for that aren't there, but mostly I can find what I need.

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.
