JFD54AN8: Calcite (Co-bearing calcite variety) with Pyrite
They could do with a bit more luster, but the color, the sharpness of the crystals and the not so usual presence of Pyrite in the matrix made me fall in love with this piece that has been with me for many years, reminding me of those trips to Morocco so full of sunshine and adventure.
