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.

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.
