This is a beautiful specimen of Blue Lighning from Arizona.  It is Shattuckite and Chrysocolla in Quartz.  It is hand wrapped in an original and one of a kind design - a truly artisan piece.  It is 2 5/8" long from the top of the bale to the wrap below the bottom of the stone.  The bail will acomodate a 4mm bead or chain.  The Iolite and sterling chain listed in our shop was designed as a match for it, but a sterling silver omega would be beautiful with it as well.
 
Beautiful American cabochons such as this one, hand made by a lapidary artist, are difficult to find, but so worth it when adding a piece to your private collection.
