18k White Gold GIA Certified 12.66ct Aquamarine and 0.24ctw Diamond Ring

18k White Gold GIA Certified 12.66ct Aquamarine and 0.24ctw Diamond Ring

This stunning ring is in excellent pre-owned condition and ready to ship!

At 12.66 carats, this GIA certified natural aquamarine commands immediate attention. Aquamarine sits in the beryl family alongside emerald, and the finest specimens carry that characteristic clear, glacial blue that ranges from pale sky to deep sea. This stone occupies the upper end of the size spectrum for fine aquamarines — anything over 10 carats in a natural, untreated quality is genuinely rare in the market. The GIA report confirms its natural origin, giving buyers the assurance that comes from the world's most trusted gemological authority.

The setting pairs the aquamarine with pavé-set round brilliant diamonds at the shoulders, totaling 0.24ctw, all mounted in 18k white gold. White gold was the right call here. The cool, neutral metal reads as an extension of the aquamarine's icy color rather than competing with it. The bezel-influenced mounting cradles the stone securely while keeping the profile clean and wearable. At 7.5 grams, the ring has a satisfying substantial feel without sitting heavy on the hand.

This is a cocktail ring with genuine collector appeal. A natural GIA certified aquamarine of this size shows up rarely in the estate market, and the combination of the stone's weight, its clarity, and the understated 18k white gold mounting makes it as appropriate for a gallery opening as it is for daily wear. Size 6.5 and can be sized by our in-house jewelers if needed.

Each piece is fully inspected and authenticated by Diamonds by Raymond Lee in Boca Raton.
