Estate French 18K Cabochon Sapphire Diamond Cocktail Ring GIA No Heat 14.59ctw

A truly exceptional French-made ring crafted in 18 karat white gold and centered by a remarkable 12.59 carat oval cabochon sapphire of outstanding color and presence. This sapphire exhibits a vivid electric blue hue with a striking internal glow and depth, further distinguished by its accompanying GIA laboratory report stating Sri Lanka (Ceylon) origin and no heat treatment—an increasingly rare combination highly sought by serious collectors.
The domed sapphire is framed by graduating, sculptural shoulders meticulously pavé-set with brilliant white diamonds, creating a bold yet refined profile that sits beautifully on the hand. French touch marks and an un-attributable maker’s mark are present, reinforcing its authentic French craftsmanship and sophistication. This is a powerful statement ring with exceptional gemstone quality and an unmistakable couture aesthetic, ideal for the collector who values rarity, artistry, and provenance.
