Since prehistoric times, people have used animal bones for ornamentation. Their relative softness lends to beautiful carvings for both detailed figurines and jewelry, often as beads. Cultures without access to ivory often used bone for similar purposes.

    Bone has a parallel fibrous structure. If the piece is viewed as a cross section you can see the remnants of blood vessels. These areas will appear round or oval and might have a dark appearance if stained or filled with a foreign substance.
