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 5.4 inches by 3.5 inches and 7 mm thick.
It weighs .32 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.
