Overview & History
Diamond engagement and anniversary rings range from modest solitaires to important platinum-and-diamond pieces and Art Deco designs. Value is driven primarily by the center diamond's four Cs and certification, plus the metal, the setting, any signed maker, and condition. Selling at auction reaches both retail buyers and the trade, often achieving strong results for fine and certified rings.
Identifying & Marks
The center diamond's carat, cut, color, and clarity (ideally GIA-certified) set the value, along with the metal (platinum, 18K/14K gold), the setting, and any signed maker. Our specialists evaluate the stone and mounting.
