Sleeping Beauty is known for its sky-blue color with no matrix although it comes in many looks. The history of Sleeping Beauty is found in Turquoise in America Part Two, 1910-1990.
 
This cab weighs 8.4 carats and measures 2cm X 1.5cm. It is not treated and unbacked. It is priced at $20 a carat or $168. I have assigned a TG of 85 or High Grade. This stone shows a deep blue for Sleeping Beauty and is very hard. I bought this cab from Greg King, well known Taos lapidary and turquoise dealer.
