This necklace makes a perfect gift for the math-loving geek in your life!
I hand cut a piece of circuit board into a circle and nestled it under a layer of clear resin, which forms a beautiful domed top coat. The circuit board charm is 5/8" (16 mm) tall. It sits with a cute math charm and coordinating Swarovski crystal bead. The necklace is attached to silver chain that is 18 inches (46 cm) long. If you'd like something longer, leave your request in the message box at checkout.
