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 also famed for being the December birthstone.
