Purple Neodymium sea glass from Italy statement pendant

This fabulous pendant has a beautiful large piece of Neodymium glass that changes color from purple to blue depending on the light it’s in. Over 80 years ago a flood in Tuscany swallowed up a warehouse full of high end glassware into a river and washed it out to sea. It’s still washing up on beaches there today. this fabulous patterned piece is wrapped in fine silver with an Argentium silver backplate and 20” Sterling silver rolo link chain.
