11.55ct Unheated Sri Lankan Sapphire and Diamond Ring with GRS Certificate

£16,000.00

An extraordinary 11.55ct natural sapphire takes centre stage in this magnificent sapphire and diamond ring. Certified by GRS (Report No. GRS2013-053918), the sapphire is confirmed as unheated—a significant rarity that places this gem among the highest tiers of collectible sapphires.

Originating from Sri Lanka (Ceylon), one of the world’s most esteemed sources for fine blue sapphires, the stone displays a vivid, luminous blue colour with exceptional clarity and life. Cut in a beautifully proportioned cushion shape with a modified brilliant/step cut, it measures an impressive 13.51 × 11.06 × 7.65 mm, offering outstanding presence on the hand.

Surrounding the sapphire is a halo of bright, well-matched diamonds that enhance the stone’s natural brilliance while giving the piece an elegant, timeless silhouette. The craftsmanship is refined, balanced, and designed to showcase the sapphire without distraction — a true statement ring suitable for both evening wear and collection-grade investment.
