I set two gorgeous fossils, fossilized dinosaur gem bone and corral in a .925 silver collar. The silver has been textured and treated with a darkened patina to show off the detail. The back is just as lovely with a replicated coral “flower” cutout. The collar is suspended from an adjustable length sterling silver chain with a lobster claw closure (total length of 21 inches). The pendant dimensions are: 2 inches wide and 3 inches long.
