Stone of the Month July 2020: Prehnite

 German Version here

Nature has reached its climax, animals and plants are full of strength and energy. The activities of the first months of the year are showing tangible results and we can enjoy our successes. Secretly nature is already preparing a little for fall and the harvest - fruits and seeds are growing and starting to ripen. Now is the time for us to collect energy for the darker and colder times of the year.

During this lively time, the pale green Prehnite helps us to pause for a moment, when repressed images and memories come to light from the depths. Unpleasant insights can be more easily accepted with its help, so that in the end we emerge from this time stronger and more confident in ourselves. The sometimes essential sober analytical approach is strengthened with the help of the stone, so that we are able to perceive the impressions from our surroundings faster and a more differentiated way.

Tumbled stones, stringed beads and much more gemstone articles for retailers and other professionals can be found in our wholesale webshop.

Discovery and naming Prehnite

The name Prehnite goes back to the Dutch mineralogist Colonel Hendrik von Prehn (1733-1785), who brought the stone from the Cape of Good Hope (South Africa) at the end of the 18th century. He had the samples analyzed by the German mineralogist Abraham Gottlob Werner (1749-1817), who recognized the stone as a new mineral and named it after Colonel von Prehn. Prehnite is thus the first known mineral which was named after a person.

The beautiful green translucent and shiny stone was still unknown and was initially identified as an emerald, but this was soon revoked because it had neither the hardness nor the unparalleled color of the emerald. After it was later wrongly assigned to prasem, peridot and even tourmaline, it was finally recognized as a newly discovered and separate mineral in 1787. Prehnite is also known under the trade names Cape Chrysolite and Cape Emerald; meanwhile obsolete synonyms are Aedelite, Chiltonite, Coupholite (Koupholite), Edelite and Triphanspat.

Effect and energetic attribution Prehnite

Prehnite helps to come to terms with oneself and to accept oneself as one is, which also increases the readiness for conflict. It brings moods and sensations to the surface of the consciousness, which subliminally influence thoughts and behavior by dispersing mechanisms of repression and avoidance. Prehnite refreshes and soothes and prevents the constant accumulation of unfinished business.

It promotes the analytical mind and increases the ability to absorb information. If you feel that you are being exploited, Prehnite helps you to care more for yourself and to come to terms with yourself.

In order to experience the effect of Prehnite, it is worn as a pendant, ring, earring or necklace with direct skin contact or carried in the trouser pocket as a tumble stone. The green gemstone is also ideally suited for laying a stone circle and for meditation.

Chakras and astrological attriubution

Depending on its coloring, Prehnite works best on the solar plexus and the heart chakras. Those with yellow coloration are assigned more to the solar plexus chakra and those with green coloration more to the heart chakra. From an astrological point of view Prehnite fits particularly well to the zodiacs Cancer, Libra and Sagittarius.
