The Marquise Watermelon Tourmaline Ring in Sterling Silver puts nature's most playful gemstone front and center. A marquise-shaped watermelon tourmaline cabochon shifts from deep pink through mossy green, with hints of red, just like the inside of a watermelon. It's set in a clean sterling silver bezel on a braided band.
It's handmade in the U.S., one of a kind, and size 6, a dainty statement ring that's easy to wear every day.
What Is Watermelon Tourmaline?
Watermelon tourmaline gets its name from its natural pink center and green edge, a color pattern created by mineral changes as the crystal grew. Every stone forms differently, so the colors and banding are never the same twice. It rates 7 to 7.5 on the Mohs hardness scale, so it holds up well to everyday wear.
Designed to Let the Stone Shine
Marquise Shape
The elongated marquise shape follows the line of the finger and shows off the stone's full color shift from end to end.
Bezel Setting
A smooth sterling silver bezel wraps the edge of the stone, protecting it from chips and keeping the ring low profile and snag-free.
Braided Band
The hand-braided silver band adds subtle texture and dimension without bulk.
