Tourmaline, sustainable gold, sustainable silver earrings, blue tourmaline, green tourmaline Absolute one of a kind earrings. I bought these stones knowing they would become a team somehow. Earrings were clearly the best solution as they allow light to shine through and illuminate the incredible colours of these tourmalines. The rustical, organic contstruction of the metal contrasts with the smooth, polished stones. The earrings comes packaged in a matt white environmentally friendly presentation box, ready to be given and received with love. All my metal is from a company which is a member of the Responsible Jewelry Council. They deal only in recycled silver and gold. They smelt their metals to the highest environmental standards, to cause the least impact on the environment. They do not deal with newly mined metals, as these metals cause much greater destruction to the environment.
