Everyone is unique -pure fine silver snowflake about 1 " held in a hammered copper dome. A fun necklace for winter any time of year for snow lovers. On silvertone chain. Hand smithed jewelry of certified green silver. Each piece is cut or cast, forged, hammered, set and polished by me. What does sustainable green silver mean in my jewelry? I start with fine silver which is the purest available -99.9% silver made with reclaimed/recycled metal or from third party certified, ethically mined metal. The company I purchase my bulk silver from recycles silver and gold from a variety of sources, has been doing this for 30 years and has won numerous environmental awards over the years. Silvertone chains are brass with silver plate. What does sustainable mean? It is a social pact with future generations. Sustainable means meeting our present needs without compromising the needs of our children.
