Measurements: Pendant is 1" X .5". The chain is 18". Handcrafted by Shirley Woodcock-Kolb. Ruby and sterling silver filigree necklace on a 18" chain. 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.
