Glaucodot, Holmquistite Halite Smithsonite Hemimorphite Trilobite

Glaucodot
Glaucodot crystal from Håkansboda, Västmanland, Sweden.
The rock concists of two intergrown crystals in a matrix of mostly sulphides. It is hard to see the crystal since it is too shiny. Either the surface is all shiny or it is black since it doesn't reflects any light.
Collected by Luziana Pederzani 1979-05-13.
3x2x1.5 cm, crystal size about 6 mm.
