This is an original and one of a kind ring. Stone has beautiful waves of clear and white running through it, stone from Oregon. The band and setting are made in certified green fine silver. Size 8 Hand smithed jewelry of certified green silver made and Oregon sourced stones available now. 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. 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.
