Silver-backed pendants of engraved ivory on sterling or gold chains sound extravagant, but these have an eco-twist: they’re made of disused piano keys. Some have wooden book boxes to travel in. The boxes too, are made of recycled materials. We've written about these pendants before, but the line has since expanded, so we've included the most recent designs.
Puerto Rico native Derrick R. Cruz is the artist behind these pieces. His studio, Black Sheep & Prodigal Sons, is based in Brooklyn, New York. Work for sale is described on his website.
