French Platinum Diamond Deco Rock Crystal Studs

A newly converted set of tuxedo buttons and cufflinks presents a refined and versatile accessory option. These French hallmarked pieces feature a platinum top and 18k yellow gold back, recently reimagined as studs with secure 18k yellow gold posts and friction backs. The diamonds are framed by rock crystal and detailed with black enamel. Available in two sizes—smaller buttons and substantially larger cufflinks—they offer a unique opportunity for a sophisticated and thoughtful mother-daughter pairing.
