A very rare, hollow, polyhedral agate cast from Brazil and the Richard Hauck Collection. This sharp, lustrous, colorless specimen is complete-all-around and is pristine. It looks like a "Horn of Plenty" with the sparkly quartz crystals and agate septae (blades) visible at the mouth and in the interior of the cast. Drusy quartz coats some of the faces. A unique, highly unusual quartz varietal specimen.
