Because recycling is great! Just think about how many reusable stuff we throw out all the time: paper that can be recycled, clothes that could make someone happy, food that could feed hungry children, and yes, this also applies to jewelry.
A good friend of mine offered me the jewelry she does not wear any longer. She collected them in a small bag and I could choose the ones that are not plastic and can be reused. I demounted them and now will reuse the beads and pieces.
This earring contains all bits of different stuff: metal coin, wooden and shell pieces, jaspis mineral fragments and the tiny rounded beads that are carved from real bone and have just been given another chance by getting recycled.
