Iridescent Pyrite, Todd’s Quarry, New Zealand

Found a home already.

This is an illustration of iridescent pyrite from Todd’s Quarry, Arapohue, Northland Region, New Zealand. This location is well-known for pyrite that grows preferentially in one direction, resulting in long crystals rather than the standard cubic habit. Sometimes these crystals abruptly change direction at right angles too.

Artwork is coloured pencils on A5 grey paper.
