Here was my first chance to see them as Magnetite Clusters. They are from Morocco. I have only seen this crystal occasionally as polished pieces. The magnetised version is called lodestone. Unfortunately in this form I don’t think you can magnetise the points!
The matrix is very soft so no soaking in water. I don’t feel the photos do them justice. Here are other specimens. If you want to wear it you are unlikely to find any so hematite bracelets and pendants are close energetically and in look.
This crystal alleviates negativity such as fear, anger and grief. Brings positive qualities such as tenacity and endurance. It is said to stimulate sluggish organs and sedate overactive ones. And beneficial for asthma, blood and the circulatory system. Read more about the shape.
Magnetite clusters are mainly bought by the geologists and the more sophisticated metaphysical buyer.
