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

This platinum 3-stone ring mounting is designed for a classic square stone configuration, featuring a 6.5 mm center stone position flanked by two 4 mm square side stone seats. Cast and hand polished, the mounting arrives ready for setting and sizing, making it an efficient choice for professional jewelers building finished pieces or working with clients on custom designs.

Crafted in the USA by America's largest family-owned findings manufacturer, this mounting is made from responsibly sourced platinum—specifically a 95% platinum and 5% ruthenium alloy—delivering the density, durability, and prestige that platinum settings demand. The standard USA ring size of 5-1/2 provides a reliable starting point for sizing to fit.
