Antique .62 carat Old Mine Cut diamond solitaire engagement ring

A billowy, pillowy .62 carat Old Mine Cut diamond with leggy dimensions. The diamond - which is well over a century old - has antique facet proportions that give it a lively, flickering brilliance. We acquired this diamond loose and opted to set it in a simple platinum setting.

Note: If you love this diamond but wish it was set in yellow or rose gold, please be in touch: we can switch it up for you.
