Sterling Silver Turquoise Large Slim Oblong Necklace, P020. This simple and sophisticated necklace is part of our Heritage handmade jewellery collection and features a stunning slim oblong piece of Turquoise stone. The vibrant greenish blue stone is framed within an exquisite sterling silver setting and the pendant is completed with a secure 18 inch sterling silver chain. 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. Kingman Turquoise is distinguished by its unique lustre, striking characteristics and sky-blue colour. Turquoise is also famed for being the December birthstone. All articles purchased from C W Sellors are lovingly and securely dispatched with our elegant jewellery packaging.
