A very colourful specimen here with two very definite deposits/generations of growth. The first is small prismatic crystals of Ettringite crystals of a few mm which have been deposited on a thin matrix, here and there on the display face one can see the terminations of the first generation peaking through. There was a second generation of small fine-grained Ettringite with a more lemon-yellow colour that filled the space between the slightly larger crystals. A great colourful specimen.
