The German Crown Jewels encompass both the Imperial Regalia of the German Kingdom within the Holy Roman Empire and the Prussian Crown Jewels, which the Prussians kings continued to use after becoming German Emperors in 1871. The German Empire had no physical Crown jewels, though a model of a German State Crown was created and used in emblems.
The term may also be used in reference to regalia of the various constitutive German monarchies that sprang from the Holy Roman Empire and later were unified in the German Empire.

The Imperial Regalia, insignia, or crown jewels are the regalia of the Emperors and Kings of the Holy Roman Empire. They are kept at the Schatzkammer Treasury in the Hofburg palace in Vienna, Austria.

Most of the Prussian regalia are on public display in the Charlottenburg Palace in Berlin. The Crown of Wilhelm II, in his role as King of Prussia, is in the Schloss Hohenzollern in Germany.

In 1871 a design and model for a new state crown was created to reflect the new German Empire. The model was based upon the Crown of the Holy Roman Empire and was kept in the Hohenzollern museum at Schloss Monbijou in Berlin, until it disappeared during World War II. It has never re-surfaced.
