Necklace / Pendant All of my pendants are created with PMC3 silver paste or sterling silver 950 & 960. I often make the pendants with the pins on the back so that you can wear it as a brooch as well. Each pendant can be worn with your favorite necklace strings (metal, leather or silk). I also provide the string materials. Some of the dark colors are done with the river of sulfur, Ag2S to oxidize the silver. I control the darkness, or texture of the silver. However, this darkening will eventually fade with its own unique patina by the person who wears them. Sometimes I add a few colorful gemstones or crystal materials.
