I use sterling silver PMC for these tiny shapes. I textured them using a process called tear- away. Each texture is unique. I draw the textures on paper and then copy them on a specific copier. The copy is then adhered to polymer clay. The paper created in this process is used the texture the PMC. Once the shapes are created I fire them in a kiln and then I polish them to create shine. Piece can be customized by types of shapes on the necklace, how many, and the type of chain and clasp.
