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 process was pleasant, I chose to purchase the stone traditional to the month of March as it is the month in which I was born.
