Boulder Turquoise is a very beautiful and unique form of Turquoise. It is natural stone with Turquoise veins, it is also known as Ribbon Turquoise. It may seem like understated turquoise but it is really a very flashy statement turquoise. Most Boulder Turquoise is found in the Royston & Pilot Mountain mines in Nevada. No wonder we like it so much, it has Royston in its veins!
