3.81ct GIA Certified Unheated Ceylon Sapphire Diamond Cocktail Ring Platinum

A substantial and luminous cocktail ring centered on an unheated 3.61-carat Ceylon sapphire in a deeply saturated cornflower blue. The stone is GIA certified and displays the characteristic transparency and brilliance that distinguishes unheated material from heated counterparts—color that moves, rather than color that sits flat.

The sapphire is round cut and sits elevated in a refined platinum mounting with a quartet of bright diamonds set in double compass prongs. The setting is high quality throughout: the stonework is precise, the prongs are properly seated, and the proportions favor the sapphire without sacrificing architectural balance. The ring carries weight and presence without reading as heavy on the hand.

The sapphire shows the expected inclusions native to unheated Ceylon material; none are visible to the naked eye, and the overall transparency reads clean. The platinum retains its finish and shows only light wear consistent with proper care.

This is a ring for someone who understands the difference between color and saturation, between heated and unheated, between Sri Lankan and lab-treated. It's a piece that rewards close inspection and a steady hand at the jeweler's loupe.
