A classic solitaire mounting crafted for a 7.5 x 4.25 mm marquise center stone, this die-struck ring mounting delivers the refined quality and precision fit that professional jewelers demand. Made in the USA by America’s largest family-owned findings manufacturer from responsibly sourced gold and platinum, each mounting arrives highly polished and ready for setting and sizing.
The six-prong head provides secure, elegant retention for the marquise shape, while the die-struck construction ensures consistent metal density and a smooth surface ideal for finishing work. 14K white gold versions use a nickel-based alloy and are rhodium plated. Platinum is alloyed as 95% platinum and 5% ruthenium. Available in three metal configurations to suit a range of client preferences and price points.
