Pinolith

Meaning and Properties

History


Pinolith (pine stone), or Austrian pinolith, is a very rare semi-precious stone. Named for its magnesite inclusions resembling white pine cones or kernels (pine nuts), pinolith is also known as pinolite, pinolitstein or in German, märbelstein. Pinolith shows a matrix radiance ranging from gray to black.


It comes from only one place in the world, a magnesite deposit located in Lower Tauern, a mountain range of the Central Eastern Alps in Austria, where pinolith was discovered in 1873.


Pinolith was mined during World War II for its high manganese content--essential to iron and steel production.

Metaphysical Properties


Pinolith is believed to be a gemstone of optimism and balance, providing a soothing, calming effect, improving self-esteem while establishing equilibrium between emotions and intellect. Pinolith is thought to promote imagination and creativity by banishing negativity and encouraging clarity of mind for positive visualization. Metaphysical adherants credit pinolith with helping them attain the highest state of meditation, finding it a useful aid for relaxation.


Pinolith is believed to activate the crown chakra and open the heart chakra to sincere love. It conducts energies that turn on the third eye. Pinolith is aligned with the astrological sign of Aries.


Geological Properties


Pinolith is a metamorphic rock containing magnesite as white crystals in a gray dolomite and graphite matrix. While dolomite and magnesite can be found in many locations around the world, this unique combination can be found only in Styria, a state within southeastern Austria. It's German name, märbelstein, refers to the gemstone's unique marbled appearance.

Proper Care of Pinolith


Because magnesite is one of its components and has similar hardness, pinolith is easily scratched, so special care should be taken in cleaning and storing this stone. Use water and a soft cloth to safely clean. Storing in a drawstring bag is a quick-and-easy way to protect the stone from scratches. It is not recommended to use ultrasonic and steam cleaning on pinolith.

Designing with Pinolith


The white and black opaqueness of Austrian pinolith makes it ideal for creating a classic look of sophistication when matched with polished or antiqued sterling silver. Pinolith's black matrix can be further emphasized in conjunction with black gemstones such as jet, onyx, black jasper and black obsidian. Pinoilith's primary natural neutral hues of white and black make it a "universal donor" that makes it a great accent for a wide of range of colorful gemstones.
