3.57 Carat Vintage Black Opal and Diamond Halo Ring in 18ct Yellow Gold


This vintage Black Opal and Diamond halo ring is mesmerizing! It’s an electric, bright blue! The way the light moves and plays within the huge Opal and shows off its blue play-of-colour is astonishing and enchanting in equal measure. Opals are unique, amorphous gems which create a magical mosaic of rainbow colours when light is reflected off the tiny, perfectly stacked, microscopic spheres which make up their structure. They're a true natural treasure and Black Opals are the most rare of any. Learn everything you need to know about them in our YouTube video
