About Diaphorite
Formula:
Ag3Pb2Sb3S8
Due to the substitution Ag+ + Sb3+ â 2 Pb2+, the chemical composition is somewhat variable (Mozgova et al., 1989; Armbruster et al., 2003).
Colour:
Steel grey to black
Lustre:
Metallic
Hardness:
2½ - 3
Specific Gravity:
6.04
Crystal System:
Monoclinic
Name:
From the Greek ÎŽÎčαÏÎżÏÎŹ, "difference", because it is distinct from freieslebenite, a supposed dimorphous form.
