Like so many of the stones I work with, Chrysocolla has been used in jewelry making and carvings since ancient times.  There are many lovely color variations in blues and greens.  This one has beautiful teal color with a dramatic darker "vein" running through it.  I framed it simply in square copper wireand added a copper bead right beneather the four wire bail.
 
Comes with a 24" faux-copper chain.
