The Vintage Solitaire in precious platinum makes an elegant setting for a one carat Passion Fire which is sold separately. It is about the width of a standard Tiffany style solitaire, at 2mm but includes a textured engraved pattern, reminiscent of pre-WWII designs. We've added a customized four prong head to set this one apart from the other Vintage styles on the market. Click Customize and please let us know how we can improve this design!
