Hemimorphite is rare in cut stones, and typically are only seen from Mexico. This stone is amazingly clean for the material, as most Hemimorphites I've seen from Mexico have obvious inclusions. There truly are few localities where one can find gem quality Hemimorphite that will cut such brilliant those as this one. This "Round" cut stone has only very very slight inclusions, and is larger than the vast majority of Hemimorphite stones from this area. A great rare stone for any collector of unusual stones.
