10 - 12 mm Opal Gems

Over 19 Years in the Gemstone Business!

Thank you for trusting us with your purchase!

Overall Rating -> 10 star ratings

Excellent prices, excellent gemstones, easy to navigating, at the checkout, only a part of my cart was paid, then I get back to my chart, and the missing gemstones were there, so I pay it.At the end of the day, I did 2 consecutive purchases, paying 2 shippings. But even with that issue, I’m sure that worth it.Thanks!

Purchase process is easy. Make the selection online and pay for it. About a week to 10 days later the stone shows up. Very easy and on time.

It was fairly easy to navigate after learning the website. Found what I wanted and it’s suppose to be 100% natural gemstones. I will test when they arrive and update my feedback
