Cartier’s Small 18K Yellow Gold Clash de Cartier Ring is an industrial-looking piece with spikes and studs galore! Made of shiny yellow gold, it is 6.5 millimeters wide and has a flat interior, while the edges have a bit of flex. In great condition with a box and certificate, it has been gently worn. This collection is said to celebrate a clash of styles, and this unique ring is a perfect example!
