Though showing some obvious cleaving at its tip, this Amhydrite crystal has otherwise excellent form. There are actually 4 or 5 crystals that make up this specimen: one large one, and 3 or 4 much smaller crystals that grow off of their larger relative. All of these smaller crystals show some heavy cleavage. All have a pale blue color, pearly luster, and a cloudy translucence. Small white calcite crystals grow on one side of each crystal. They are in the form of small scalenohedral "dogtooth" crystals, and have a slightly gray tinge to them. Other than these calcites, there is no host rock or other material to speak of.
