Casket (decorative box) in the context of "Bone carving"

A casket is a decorative box or container that is usually smaller than a chest and is typically decorated. In recent centuries they are often used as boxes for jewelry, but in earlier periods they were also used for keeping important documents and many other purposes. Many ancient caskets are reliquaries, for both Buddhist and Christian relics.

A tall round casket is often called a pyxis, after a shape in Ancient Greek pottery; these were popular in Islamic art, often made from a section of the ivory tusk of an elephant.
