Magma. The 'Magma' features three matching beads crafted from fossil dinosaur bone, the last legacy of an Apatosaurus that walked the earth 100 million years ago. Found in the American west, each piece is truly unique, so no two beads will ever have the same pattern. Dinosaur beads are flanked by sterling silver accents, and the clasp is also sculpted sterling. Frosted black onyx beads create the backdrop for this remarkable story.
