FILIGREE CATHEDRAL SEMI-SET RING

Platinum alloy serves as the structural foundation for this semi-mount, which is engineered with a high-profile cathedral design to elevate a 1.5-carat (7.0 mm to 7.5 mm) center stone. The cast shank features intricate openwork filigree and scrollwork motifs, complemented by milgrain-beaded borders and flush-set melee diamond accents totaling approximately 0.12 carats. A standard four-prong basket head is integrated directly into the upper cathedral bridge, providing secure containment and optimal light entry for the primary stone.
