Here is a very nice 'ball of garnet' from Imilchil, displaying dodecahedral-trapezohedral crystals with delicate silky lustre and rimmed with green epidote, which marks a reactional texture.
The clear colour underlying matrix is made of plagioclase felspar and retains an altered round crystal shape: possibly leucite or analcime, that was subsequently totally pseudomorphed to plagioclase (most probably close to the calcitic end-member anorthite).
A quality Moroccan garnet, carefully selected from a 2022-2023 discovery.
