Vintage Old Mine Cut Diamond and Onyx Ring vendor All the diamonds have openA vintage ring crafted in 14k white gold, set with a 0. 50 carat old mine cut diamond framed by a polished onyx surround. The design relies on contrast and clean geometry rather than ornament, using the depth of onyx to emphasize the presence of the diamond. The old mine cut, with its broad facets and softened light return, reflects an earlier style of cutting that favors character and structure over brilliance. Size 11.
