• (Fig. 1), as is well known, is constructed from a rhombohedron of
• As in the other rhombohedral carbonates, the crystals possess perfect cleavages parallel to the faces of the rhombohedron.
• Its crystals have formed in a textbook rhodo shape--rhombohedron--very geometric, very distinct, with nice sharp, flat faces.
• Distinct crystals are somewhat rare; they have the form of the primitive rhombohedron (rr '= 72° 20'), the faces of which are generally curved and rough.
