Anyone know anything about this badge. Any history, is it collectable?

Sorry pic is not very clear but it says Kreuzer Karlsruhe (the battle ship pictured) enamel on the front. On the back it has the letters H. B. at the top and at the bottom the letters GES.GESCH-. Has a pin on the back. Any help most welcome.
