Crystal Skull Found in Berlin

We would like to show this outstanding crystal skull, full of energy  and power.
If you look at it you see the “whole universe” in it.
The head looks very alien and is made out of an piece rock crystal.

It looks very antique and highest quality handmade. The head was  restored in former times. The crystal skull is 7 x 12 x 7 cm. It bears a writing of a collection “Inv. 23.J(T?) 1917 A v Bode”. The whole object is definitely old and could be in the private  collection of Arnold Wilhelm von Bode, the famous German museum  director. If somebody could send us further informations, that would be very  helpful. Thank you Martin
