Copper Marquise NecklaceThis makes a perfect gift for the geek in your life! I hand cut a piece of dark brown circuit board into a marquise shape. I carefully removed the brown solder masking to reveal the bright copper traces underneath. The circuit board nestles under a layer of smooth resin, which forms a top coat that is beautiful and protective. The pendant is about 1 3 4" (4. 5 cm) tall including the hammered square element. This will come on an 18 inch (46 cm)
