Cantera Opal Wire Wrapped In Sterling Silver

This is a very pretty cantera opal 14x12x9mm... reminds me of cotton candy with light pink and light blue hues but when you see this in the light it POPS with a rainbow of colors. I am having a very hard time photographing this piece.  There are no surface cracks on this piece but a few cracks in the opal matrix under the opal layer- see up close photos. Video on my Instagram @leetwraps This opal is from Alan Dean- Tourmaline Kings... All sterling silver oxidized and polished... free flow design. Comes on 20 inch chain as seen in photos and in a gift box.
