Item number: 27022

Well, allargentum is not a common mineral! It looks very much like silver but, unlike silver, it has cleavage. Silver does not! At Cobalt, allargentum occurs in masses and as lamellae in native silver. Note the triangular cleavage markings on many of them. This piece is solid allargentum/silver that shows some cleavages of allargentum in allargentum or as lammellae in silver. Rich and unusual! Rare!
