Black Widow is located in the Candelaria Hills of Nevada and has a long history. It is currently mined by Helen and Richard Shull and Philip Chambless.
 
This cab weighs 12.7 carat and measures 2.25cm X 1.50cm. It is priced at $90 a carat or $1143. It is not treated and is backed. I have assigned a TG of 91 or GG. Black Widow of this grade is very rare. I bought this cab from the Helen and Richard Shull. White spot is camera flash.
