This very different necklace, actually resulted from a mistake in the kiln firing. I unknowingly used a glass that was transformative ( changes colour in the kiln ), behind the dichroic glass layer. The result, is both unusual and I think really striking as well as quirky! To me it looks like a fossil stcking out from the underlying rock. That makes for a very pleasingly aesthetic necklace . Sold with a choice of 16 18 or 20 inch silver plated snake chain. Gift wrapped.
