No Heat Teal Sapphire & Diamond Ring | 3.15ct Oval | Marquise & Round Diamonds | 18k White Gold

The Color That Cannot Be Manufactured

Teal sapphires are among the most coveted colored stones of the moment — and this unheated 3.15ct oval shows exactly why. Its color sits at the precise intersection of deep ocean blue and forest green, shifting subtly with the light in a way that no two observers experience quite the same. It is a color that exists nowhere else in nature quite like this.

Unheated means the color is entirely natural and untreated — no enhancement, no alteration. In the world of colored gemstones, that distinction significantly elevates both value and rarity. What you see is exactly what the earth created.

Flanked by a delicate arrangement of marquise and round brilliant-cut diamonds (approx. 0.50 ctw), the design frames the sapphire with precision and elegance without competing with it. Set in 18k white gold (3.40 grams), the cool metal is the perfect complement to the stone’s blue-green depth.

Brand new. Never worn. Size 5.
