Vintage Platinum Oval Sapphire Trilliant Diamond Cocktail Ring NO HEAT GIA 13.05

A spectacular circa 1960s cocktail ring of exceptional quality, finely crafted in platinum and centering an important 13.05-carat natural, unheated Ceylon sapphire. The gem exhibits a mesmerizing violet-blue hue with delicate lilac undertones — a shade highly sought after for its refinement, vibrancy, and crystalline depth. The sapphire material is extraordinary: a true crystal gem of near-flawless clarity, revealing only a minute inclusion beneath a prong, confirming its natural origin.
Surrounding the sapphire is a halo of approximately 3.00 carats total weight in vintage trilliant and round brilliant-cut diamonds, all well-matched in G–H color and VS1–VS2 clarity. The overall composition reflects the timeless elegance and symmetry characteristic of fine mid-century design. Substantial in weight and presence, this jewel embodies the sophistication and craftsmanship that define the most coveted creations of its era.
