“A squareish block of dark grey matrix has an internal vug and one face covered in needle quartz to around 4mm tall. In both these areas there are small but perfect & transparent erythrite crystals to 5mm max, and some bright pink balls of Roselite - 1.5mm max (not in the vug.)Very photogenic and lovely to study under a loupe.”
