Matthew Charley Spiny Oyster Ring is a rare, one-of-a-kind statement piece featuring a deep orange spiny oyster gemstone framed in hand-stamped sterling silver. The vivid stone, formed from the shell of the Spondylus mollusk, brings warmth and natural character to the bold Southwestern design. An exceptional example of artisan silversmithing, this distinctive hallmarked piece stands beautifully on its own.
