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 our Turquoise and Whitby Jet jewellery is designed and crafted within our very own workshops in Ashbourne, Derbyshire where a team of skilled craftsmen transform the natural stones into these stunning pieces of jewellery.
