Beautiful colors of blues and greens from this solid Lightning Ridge Australian black opal. Beautifully cut with a mirror finish polish, I set this gem into a solid 18ct white gold hand made 4 prong setting with six .005 carat HI color VS clarity brilliant cut diamonds set into the shoulders highlighting. This wonderful solid opal measures 11.50mm X 5.62mm and of course this solid black opal ring comes gift boxed, and what a perfect gift this would be, or perhaps for the lucky lady it will become a solid opal engagement ring. **********This gorgeous ring is currently size US-6.5, UK & AU size N, but we may be able to resized to fit, please email and let us know your finger size. **********To watch a movie of this magnificent ring cut and paste into your browser: https://youtu.be/7lWN88PbOD4 **********Shipping to the US usually takes 5 to 12 business days but expedited (3 to 5 day & 2 to 4 day) may be available.
