Turquoise Information: Orvil Jack
Orvil Jack discovered and developed the mine in northern Nevada that bears his name. The area where the mine is located is called the Blue Ridge in Crescent Valley. The rare yellow-green color of the turquoise comes from the zinc content. Mr. Jack is now deceased, but his daughter continues to manage the mine. Only a small amount is now being produced, and the turquoise is considered very collectible due to its rare color and scarcity.
