Sterling Silver Turquoise Toscana Marquise Stud Earrings. E1124. These contemporary stud earrings are part of our Toscana collection and feature marquise shaped cabochons of the finest natural Kingman Turquoise. The striking gemstones are simply and elegantly framed in sterling silver and completed with classic post and butterfly fittings. 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: 20mm x 8mm.
