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

It features a classic cocktail-style mounting on a friction post, ideal for securely displaying square faceted stones.
