Getting my dream engagement ring! Australian semi-black opal with diamond halo.

Before anyone starts, I'm well versed in the special care an opal ring needs. This is an Australian Mintabie semi black opal with amazing color play surrounded by natural diamonds. It's not hydrophane and can get wet and will not be worn everyday. I'm a bit of a collector and have had Aussie opal jewelry for years- it lasts if well taken care of. BUT NEVER LIKE THIS! My man did so good!!!!!
