The pictures didn’t do justice to the fire of this opal. There is purple, blue and even a little red. Can’t wait to have this set into a pendant.!

I have bought several beautiful Australian opals from opalgalaxy and each one has been more beautiful than I ever could have expected. This will make a beautiful ring which I will have mounted in a shadow box type ring so the opal will be protected.

Arrived quickly. Absolutely beautiful opal. I'm so glad I decided to "go for it." This was a lot of money for me, but I think I have finally found the opal I've been looking for (after several tries). Thank you so much.
