This large beautiful gemstone is fossilized dino bone. What a beautiful array of colors minerals can create inside the cavities a million years later. Very unusual piece and so lovely to work with! The setting of this gem has certain simplicity, yet has six claws to secure the stone. Adding gold and silver balls to each side to soften its look, the band is spiraled to create a more original look to this semi-industrial look. This design is meant as a statement piece on your hand, bold and beautiful!
