Measurements: Pendant is 1.5" X .75" on an 18 inch chain. This sterling silver necklace with a black pearl pendant was handcrafted by Shirley Woodcock-Kolb. "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."
