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

Die struck for superior metal density and durability, this mounting arrives highly polished and ready for stone setting and sizing. Crafted in platinum alloyed with 5% ruthenium for added hardness and wear resistance, it ships in standard USA ring size 6.
