This charm is made from recycled sterling silver scraps that have been melted down into a solid river rock shape. I than stamp on an original pattern that will always be one of a kind. The finish is achieved by adding a patina and than tumbling in special media for around 12 hours. This charm measures 7/8" from top of bale to bottom of piece and measures .5" wide. The bale measures 4mm on inside diameter. Every marking on my hand stamped pieces is like a brush stroke on a painting to create a picture. The stamps that I use are all custom made by me to create my own original designs. It often takes several separate strikes with multiple stamps to create a picture. All my jewelry is one of a kind and made to provide a sense of comfort and hope for the one wearing it. I put a lot of love into all my pieces and they are each different like the ones wearing them. All my jewelry is solid Sterling Silver and/or Copper. No chemicals are used to coat, nor glues used for joints or attaching stones. Any joining of metals is with silver or copper solder, depending on the metal.
