Believe it or not, this ring is actually made from dinosaur bone, meteorite and gold, a very unusual blend of unique materials. According to its designer, we’re talking about genuine dinosaur leg bone. A certificate of authenticity is provided when you purchase it. The space rock material comes from the Gibeon meteorite, a rock that measured about 13 feet by 13 feet by 5 feet thick and weighed at least 26 tons when it plunged to Earth. No matter how you look at it, this ring is an incredible creation.
