Goethite after Gypsum on Gypsum from Lavrion Greece! Two crystals of Gypsum covered with a thin layer of Goethite as a pseudomorph but the crystals of Gypsum are still inside and are not yet altered! The white matrix is massive white Gypsum. Apart from the main crystals and the beautiful contrast with the matrix, small pieces of the pocket are scattered all over the pieces in between and over the main crystals, as if an explosion took place inside the pocket! Beautiful specimen with impressive display!
