Andradite (Demantoide) Soghan, Baft District, Kerman Province, Iran.

At least 15 specimens are included on mindat but this one is very different while all others can be grouped in two similarity groups. I am wondering if this is really a pseudomorph and if any more like it are known.

The child photo http://www.mindat.org/photo-500038.html suggests it could be either a pseudomorph or a growth feature.

It might perhaps be a pseudomorph, or it might be just a random growth shape. The human mind has a strong tendency to try to attribute straight line geometry and familiar images to random shapes - That's how we got constellations in the sky and "canals" on Mars. If planar surfaces are smooth enough, one can try measuring angles and see whether they match a crystal shape, but when surfaces are as rough as this I fear any measurements would be little better than guesses. But it is nevertheless a beautiful garnet specimen!

base (the underside) looks as it was peeled of from some sort of matrix but there is no matrix material present.
