Hammerstone, Hydrogrossular GarnetAbout this object
This is a piece of hydrogrossular garnet, the telltale battering marks on one edge of this stone indicate that it was used as a hammerstone.
Hammerstones are used to flake off pieces of another stone in the process of lithic reduction, often to make tools. Because of this, hammerstones need to be hard and hydrogrossular garnet, at 7 on the Mohs hardness scale, fits this requirement. Material such as this is hard enough to work pounamu (nephrite jade, bowenite, and serpentinite) which Te Wai Pounamu (the South Island of New Zealand) is well known for.
