Measurements: pendant is .6 inches long and on an 18" chain. Sterling silver necklace with heart silver set dichroic pendant. Handcrafted by Shirley Woodcock-Kolb. Sterling Silver chain. "I incorporate fused glass, precious metal clay, stones and porcelain into my fabricated designs, and especially enjoy doing my own lapidary work. Although I have many standard designs, my work is always changing and progressing as I find myself drawn to new challenges. I developed my distinctive filigree technique through experimentation, beginning with a silver baby cup that was given to me and that I recycled into a bracelet. My silver and gold also comes from a reputable refinery that was formerly located in New York State, and features Harmony recycled materials."
