WOW! This is quite simply one of the most beautiful pieces I've ever seen. I decided to call it "Cathedral" because it reminds me of all the wonderful stained glass windows in so many of the cathedrals I've visited around the world. "Cathedral" is composed of wonderfully handcrafted pieces of dichroic glass and accent stones, all set in solid .925 sterling silver. It's adjustable from 16" to 18".
