Pinolith or Pinolite Lapidary Cabbing Rock Stone Slab
This lovely and very rare material is known as Pinolith or Pinolite.
This natural unpolished semi precious stone slab is 7 inches by 4 inches and 8 mm thick.
It weighs .62 lbs. and is already coated with Opticon, a surface hardening resin for easier cutting.
This very rare material was actually first discovered in 1873 and comes from only one location in the world-the magnesite deposit at Sunk, Hohentauern, Niedere Tauern, Styria, Austria.
It is a metamorphic rock containing magnesite as crystals in a dolomite and graphite matrix.
It is named Pinolith because the magnesite inclusions resemble pine cones in shape.
This material is a 3.5 to 4.5 hardness.
