Black Diamond Eternity Rings
A black diamond eternity ring is a striking departure from a row of white stones: opaque, high-lustre and graphic, especially set in white gold or platinum where the contrast is sharpest.
Black diamonds are real diamonds, so they take everyday wear well, though their dense inclusions make them a little more prone to chipping than a clean white stone. Compare a conventional row in our diamond eternity rings, or read how many diamonds an eternity ring needs before deciding on coverage. We source ethically, price transparently, and include complimentary resizing for a year — and you can talk it through with us before you commit, at no cost.
