I waited to find the perfect full cut heart-shaped diamond to make this ring. Not only is this black diamond a whopping 4.67ct, it's also 100% natural/untreated, the perfect mix of opaque black and transparency- you can see galaxies if you stare close enough! I had a very plain 18k yellow gold setting made for it as to not distract from the main feature. It can be stacked with a black diamond infinity band or nesting crown ring to fancy it up (currently working on one to go with it). This would make an incredible engagement ring or a really really nice gift to oneself :) Heart measures 10.3 x 10.2 x 5.3 mm. Ring size 6.
