Bisbee is a famous turquoise mine. The story is found in Turquoise in America Part Two, 1910-1990. This turquoise came from Glen Hogan and was cut by me.
 
This cabochon weighs 14.6 carats and measures 2cm X 1.5cm. It is not treated and backed. It is priced at $15 a carat or $219. I have assigned a TG of 70 or MG Mid-Grade.
