Genuine dino fossil key chains, featuring actual petrified dinosaur bones that are millions of years old. Yes, you can own an affordable piece of paleontological history and carry it with you everywhere! These also make fabulous gifts, as you won't meet too many people who already have a raw piece of fossilized dinosaur on a key ring. The stones range from just under 1 inch (2.2 cm) up to 1 1/3 inches (3.5 cm) long. Each stone is unique, and unpolished; the photos show a sample of the variations available. The metals are steel and a silver-tone alloy. The key rings are 1 inch (2.5 cm) across, while the chain portion is a bit over 1 inch. Please note - these key chains have no elements handmade by me, unlike most other items on my website. They are manufactured by one of my trusted suppliers. Fossils can be fragile, so please handle these with care, and do not drop them. Some small bits may shed off the bones from time to time when in use.
