Circuit board strips in red, orange, yellow, green, blue, and purple were arranged to create a mosaic-y rainbow. The circuitry rests in a sterling silver setting and is protected by a glossy coating of epoxy resin. The hand soldered pendant is 1.3" inches (3 cm) tall and is attached to an 18" (46 cm) sterling silver chain. This is a very lightweight but fun necklace to wear. This is a one of a kind necklace (OOAK) so you will receive the exact necklace shown in the photos. Longer or shorter chain lengths are available upon request- just leave a note at checkout with the length you'd like. This sterling silver necklace is made from recycled silver and chain sourced in the United States. This will come nicely wrapped in a black gift box as shown in the last photo. _________________________________________________________________ All items are shipped in a black cotton-filled gift box for protection and wrapped in bubble wrap.
