This Custom Cut Octagonal Blue Montana Sapphire is a unique One-of-a-kind American Treasure! A work of art from start to finish, it was precision cut by a husband and wife team out west who only cut a few stones a year. This light to medium blue gem is mesmerizingly beautiful. Open-work Art Deco inspired design elements add that perfect vintage touch. With the rich warmth of the Rose Gold adding a depth of color to the stone for an exceptional unity of design and materials that can only be achieved in a one of a kind jewel such as this carefully crafted ring.
