The site provided lots of detail, factual data, and good photos. I also like the availability of searching by price range as well as by the type of stone.

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.
