Sterling Silver Turquoise Marquise Ring. R404. This simple and stylish ring is part of our handmade Heritage jewellery collection. It features a highly polished cabochon of the finest natural Kingman Turquoise. The hand carved gemstone is set in a marquise shaped setting and completed with a classic sterling silver band.  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 which is recognised as one of the oldest and largest Turquoise mines in America. The mine is also 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 6mm x 11mm, width of band 3mm.
