Why Buy Oval Shape 18x13 Mm Gems from GemSelect?
GemSelect Certified Store ReviewsGemSelect: Over 22 Years in the Gemstone Business! Thank you for trusting us with your purchase!
Overall Rating -> 10
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.
