Nunderite (Nundoorite) Slabs
Nunderite was mined out years ago. It came from a single source,
Nundoora Station, New South Wales, Australia. It is not a true jasper,
but instead is a aegirine-orthoclase syenite. Nunderite is nice and
hard and quite uniform in pattern, color and structure. It cuts like
most jaspers and takes a fine polish with diamond, or aluminum oxide.
Mohs hardness 6.5.
