Design & Construction
The platinum mounting showcases exemplary Art Deco craftsmanship with hand-crafted cluster design. The cushion-cut sapphire sits in a bezel setting with milgrain border, creating refined frame that protects the stone while allowing maximum light entry. A scalloped halo of old European cut diamonds surrounds the sapphire in individual collet settings, creating dimensional flower-like frame. The substantial 17.7 x 15mm ring face delivers impressive presence on the finger. Openwork filigree shoulders feature decorative metalwork that allows light to pass through while maintaining structural integrity. Milgrain beading outlines edges throughout, adding tactile texture characteristic of early 20th century fine jewelry. The platinum construction provides both durability and neutral color that enhances the sapphire's rich blue hue.

About The Setting
This ring exemplifies Art Deco design from approximately 1920-1930, when cluster settings and geometric precision dominated fine jewelry. The combination of substantial center stone with delicate diamond halo creates classic proportions. The use of old European cut diamonds adds period authenticity, as these hand-cut stones feature the chunky faceting characteristic of pre-modern brilliant cutting. Platinum's strength allows for intricate filigree work while providing secure settings for valuable gemstones. The milgrain detailing requires skilled hand tooling to create the tiny bead borders that became signature elements of Art Deco jewelry. This ring represents investment-quality construction with museum-worthy Ceylon sapphire as centerpiece.
