Berkshire | 1.59ct Starbright Oval Montana Sapphire Ring

SKU: C21001

Never have I ever seen a Montana Sapphire with so much personality... This 1.59-carat Oval Bi-Color Montana Sapphire features two shades of denim blue and a radial carving on its underside that radiates through the stone. Set east-west in 8-prongs on an 18k recycled yellow gold band detailed with diamonds and milgrain, this ring is made for the woman who appreciates the finest details. 



About the Berkshire Style:


Inspired by my time at college in the Berkshires, this style requires a close study. This style represents a town set in an idyllic landscape of rolling mountains that are captured in the curved lines of millegrain that flow along the band.


The Berkshire reveals more details with every look. Viewing the ring from multiple perspectives, you can see layers of millegrain, baguettes set perpendicular to the run of the band, and tapering forms that guide the eye up and around the center stone.



About the Sapphire:


This ring features a central bi-color Montana Sapphire that displays two tones of blue. The Sapphire was cut by renowned gemstone artist John Dyer. Dyer is a master gem cutter who is celebrated for his artistic ability. He is the recipient of over 50 elite gem-cutting awards, including a multi time winner of the AGTA Spectrum Awards.


Every John Dyer gemstone is a unique work of art. John Dyer studies each piece of gemstone rough individually to determine the best way to maximize the gem's beauty and brilliance. He releases the hidden allure of each gem through innovative, proprietary cutting styles.


Montana, known as the Treasure State, is rich in many mineral and gemstone sources, including sapphires. Gem-quality sapphires were first found in Montana in 1865 by gold rush prospectors who found the gems in gravel along the Missouri River. These gems came in a wide variety of fancy colors, including a range of blues and greens, purples, lavenders, pinks, yellow, and a host of other hues. With a hardness of 9 on the Mohs scale, only diamonds and other sapphires can scratch a sapphire. This along with the beautiful hues make it one of the most durable gemstones to use in everyday jewelry. Montana Sapphires are guaranteed to be sourced under safe working conditions using environmentally responsible principles.
