The Blue Ridge turquoise mine, also known as the Orvil Jack mine, is located in Lander County, Nevada. It was claimed by Orvil and Bessie Jack in 1956. The mine is notable for its distinctive turquoise, especially the early finds which featured spider web matrix or came in nugget form.
In the 1980s, Orvil Jack discovered what is referred to as Orvil Jack turquoise, which is typically characterized by a green hue. In contrast, Blue Ridge turquoise is generally known for its translucent blue nuggets with dark matrix patterns. Much of the turquoise from this mine is often stabilized or enhanced to improve its durability and appearance.
Regarding the turquoise labeled as "Blue Ridge" from China, information appears to be limited, and it seems to be less available in the U.S. market today. The original Blue Ridge turquoise from Nevada, with its rich history and unique characteristics, remains highly valued among collectors and jewelry makers. If you're seeking more specific details about the Chinese version, it might require direct inquiries with suppliers or collectors who specialize in international turquoise.
