9ct Yellow Gold Turquoise Toscana Overlapping Marquise Ring, R525. This contemporary and classic ring is part of the Toscana collection designed and made by C W Sellors. The piece features a marquise Turquoise gemstone set within an overlapping curved 9ct yellow gold design which gives the ring a modern and unique look.  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: Turquoise; 9mm
