"Etsy is full of sellers who use reclaimed and upcycled metals for necklaces, rings, and bracelets to match any personal style, but seller Ash Hilton uses recycled and sustainably-mined metals, like the sterling silver in these drop earrings.

Hilton, whose work is sold in galleries in New Zealand, is also developing a technique for turning "washed-up gold" from the country's beaches into a fully fabricated metal that can become new jewelry made in a closed-loop system."
