Godber Burnham is considered a classic Nevada turquoise. The story is found in Turquoise in America Part Two, 1910-1990.
 
This cabochon weighs 11 carat and measures 2.5cm X 1cm X 4mm. It is priced at $100 a carat or $1,100. It is not treated and is backed. I have assigned a TG of 92 or GG. This cab shows the most rare highest grade of Godber Burnham. I purchased this stone from the miners Bruce and Jerri Woods. White spot is camera flash.
