ID: CC13454
A group of mustard-caramel-brown Ettringite crystals grow on and into a pinkish-cream porous carbonate matrix.  The largest crystal measures 4.5 x 0.9 x 0.5 cm and the two main crystals are well terminated from the Wessels mine at Hotazel in Northern Cape Province, South Africa. On examination of the bases of a few crystals, this dark colour of Ettringite is seen to be a 0.5 mm thick rind on what are more glassy, colourless to pale lemon-yellow crystals that form the cores.  An interesting specimen and a good example of the species.
