I purchased 4 gemstones in different sizes to be able to make a family ring for my granddaughter. I got exactly what I saw and they are absolutely beautiful! Shipping was quick compared to other gem stores I have dealt with! I will definitely order more stones from your company, as I am a collector and have several stones. You are my new go to company in the future

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.
