It's easy to say that this is the oldest piece we have in our collection–a rare, very fine example of an agatized dinosaur bone fossil! This stone is millions of years old, long predating the existence of human beings. It has an other-worldly quality with its organic shapes and form that point to its prehistoric age. The 14k yellow gold setting is handmade to perfectly bezel-set the oddly shaped stone. Its simplicity subtly frames the stone, a natural work of art! The ring is a size 11 and may be resized up or down upon request.
