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

A precision-crafted 6-prong round solitaire mounting built for professional jewelers who demand consistency, quality, and a finished look straight from the bench. Designed to accommodate a 4.5 mm center stone (approximately 3/8 carat), this die-struck mounting arrives highly polished and ready for setting and sizing β€” saving valuable bench time.

Made in the USA by America's largest family-owned findings manufacturer using responsibly sourced precious metals, these mountings are available in three metal configurations to suit a range of client preferences and price points. The standard ring size range of 6 to 6-1/4 makes them ideal for the most common sizing requests.

14K White Gold uses a nickel-based alloy and is rhodium plated for a bright, white finish. The two-tone option pairs a 14K White head with a 14K Yellow shank for a classic contrast look. Platinum is alloyed at 95% platinum and 5% ruthenium for durability and purity.
