Fluid, sculptural, and inspired by the movement of water, the Wavecrest Ring setting wraps softly around the center diamond in a smooth, flowing silhouette. Designed with the quiet strength and natural curves of Lake Michigan and the Great Lakes in mind, this modern solitaire is crafted in solid 18k gold or platinum for an effortlessly organic feel.

Pictured here with a 1.50ct round lab diamond center.

At Plum, every diamond is 100% lab-grown, ethically sourced, and carefully selected for exceptional quality. Our rings are crafted using premium materials, including recycled precious metals whenever possible, and are produced in our certified-responsible manufacturing facility with rigorous quality standards. Unlike mass-produced settings, our mountings are thoughtfully made for lasting durability, everyday wear, and long-term integrity.

Measurements and carat weights are approximate. We craft rings to strict tolerances. However, keep in mind that all Plum rings are set, polished, and finished individually by hand, so slight variations are normal.
