This unique resin necklace is a 3" oval pendant made with sand from Horseneck Beach in Westport MA with 3 dangles of sand resin shells accented with amber glass beads.
Neckwire is a 17" memory wire with amber glass beads and curved silver plated hollow  tubing, lobster claw clasp and 3" extender.
Lightweight resin, this necklace weighs only 1.9 oz.
 
When the silver plating tarnishes, it should be cleaned with toothpase as silver polish will remove the finish.
