Cerrillos turquoise comes from mines around Cerrillos New Mexico. The story is told in Turquoise in America Part One 1890-1910.

This cab weighs 54.1 carat and measures 4.5cm X 3cm. It is priced at $15 a carat or $811. It is not treated and is backed. I have assigned a TG of 80 or HG. I purchased the stone from Philip Chambless who mined and cut the stone.
