Ambas Aguas

There are several small quarries and mining claims nearby which are worked for pyrite, often occuring as twinned cubes or pyritohedral (pentagonododecahedron) crystals.

Some of these crystals are extremely aesthetic and extremely sharp and well formed. ‘Iron cross’ and ‘pinecone’ formations are of particular interest.

The matrix is typically marlstone, sometimes with gypsum or cookeite. It is extremely brittle, and its very common for crystals to fall out of the matrix, meaning there are many repaired specimens from this locale – it is up to you whether you consider crystals glued back into their matrix ‘offensive’ within your collection.

There are some pay to dig locations around the area, and I’d personally quite like to visit sometime!
