Description
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 — 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.
