Cypriot agate scepter head, Circa 950 BC

Scepter and mace heads are well-attested Cypriot implements, but this example is exceptional in the magnificence of its material. The head itself is set on an iron shaft. During the Late Geometric and Archaic periods, rulers of the major centers of Cyprus gained considerable wealth from natural resources, notably copper, and from active trade, especially with the Phoenicians.

Or, a fitting topping to a wizard's staff.  Gandalf would approve.
