Description

Made with certified recycled precious metal. Our silver, gold and platinum is refined from certified recycled content rather than newly mined ore, through refiners audited by outside parties. How we source our metal

Use this head to carry a round center stone on a ring or pendant, with a peg base that locates and fixes the head into a tube or shank at the bench. Four cast prongs hold the stone, and the peg keeps the head square on the mount. Available in 14K white gold, 18K white gold, and platinum across twelve stone sizes, from .25 ct (4.0 mm) through 3.5 ct (10.0 mm).
