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
These die-struck 6-prong solitaire ring mountings are precision-crafted to hold a 5.5mm round center stone — approximately 5/8 carat in diamond weight. Ready for setting and sizing right out of the box, each mounting arrives highly polished and is available in three metal types to suit your client's preference or your bench requirements.
Made in the USA by America's largest family-owned findings manufacturer, these mountings are produced from responsibly sourced precious metals. The die-struck construction ensures consistent, precise geometry and superior metal density for a durable, professional-quality result.
14K white gold uses a nickel-based alloy and is rhodium plated. Platinum is 95% platinum and 5% ruthenium. Standard USA ring size range is 6 to 6½.
