9ct White Gold Turquoise Oblong Twist Ring. R001. This contemporary ring is part of our Heritage jewellery collection and features a hand carved and polished cabochon of exquisite natural Kingman Turquoise. The gemstone is expertly set in a contemporary twisted design of solid 9ct White gold. We hand-select only the finest quality natural turquoise, which we cut and polish to perfection in our Derbyshire workshop to produce beautifully handcrafted turquoise jewellery. We source our turquoise gemstones from the famous Kingman mine, in North Western Arizona. The Kingman mine is recognised as one of the oldest and largest turquoise mines in America, widely known for producing highly collectable gemstone grade turquoise. Kingman turquoise is distinguished by its unique lustre, striking characteristics and sky-blue colour. Turquoise is the December birthstone. All articles purchased from C W Sellors are lovingly and securely dispatched with our elegant jewellery packaging. Dimensions: Cabochon 9mm x 5mm, Band Width 2mm.
