The Aquarelle Portrait Cut Montana Sapphire Halo Ring is crafted in our studio from rich 18K gold. At the center of this ring is a one-of-a-kind 2.69ct Montana parti sapphire in a portrait cut that shows off the stone’s internal streaks of blue and orange. The elongated cut and transparent body give the stone a soft, open quality. A frame of teal sapphires adds delicate color and contrast. 18K gold | Portrait cut parti sapphire | Brilliant cut teal sapphire Total portrait cut sapphire carat weight: 2.69ct Total teal sapphire carat weight: ~1.7ct Band width: 4.2mm
