Orvil Jack | Blue Ridge Turquoise Mine

Orvill Jack discovered and developed the mine in the northern Nevada, known as Crescent Valley, that bears his name. This claim is actually made up of two mines: when the blue turquoise is mined, it is called the "Blue Ridge Turquoise Mine." When the yellow-green “fausite”' is mined, it is referred to as "Orvil Jack Turquoise." The rare yellow-green color of the turquoise comes from the zinc content. Mr. Jack is now deceased, but his daughter Grace Jack Wintle continues to manage and work the mine, although it is now operated primarily as a gold mine. Only a very small amount of the yellow-green variety is now being produced, and is considered very collectible due to its rare color and scarcity.
