Eye catching sterling silver pendant inlaid with red coral, sugilite and red dinosaur bone by Mark Hileman. The red cell dinosaur bone is well agatized, creating a fairly hard stone that takes a good polish. There are also some neat calcite crystal cells surrounded by the black cell wall matrix. This Utah dinosaur gem bone came from the Colorado Plateau and was a living animal during the Jurassic Period around 144 to 208 million years ago. The pendant measures 24mm long and is 9mm wide at bottom. Comes with a black leather cord with silver clasp.
