Great ring

I love this ring. I’ve purchased the 6mm and now the 4mm. They make great rings with the opal inlays. Opal and findings is great to order from as well. The 4mm needs small opals to place in them but there are great as stack rings.

Love these products!

I’ve purchased from Opal and Findings at least 4 times and I absolutely love the opal. The color and sparkle is just gorgeous!! The service is top notch! I was missing a bulk pack of rings and a new package was sent the same day, no questions asked.
