Magnetite

 It is a stone to bring about a feeling of invulnerablity.  It strengthens the body, heart, mind and spirit

Also known as Lodestone or Magnetic Hematite

Spiritually and mentally, it attracts love, commitment, loyalty and stability  
It alleviates negative emotions such as fear, anger and grief

Physically, scientists have discovered evidence that magnetite exists in the human brain.  It is theorized that it may play an important role in long-term information storage
It is an anti-inflammatory and relieves muscle aches and pains
It is beneficial for asthma, the circulatory system, skin, and hair
It stimulates sluggish organs and sedates overactive ones

IMPORTANT NOTE:  Magnetite should not be worn on the body if you are pregnant, or if you have a pacemaker or defibrillator, without first obtaining the consent of your physician.

**Magnetite may form a yellow-brown rust coating if washed or kept in a moist area. If washed, it should be dried to prevent rusting. Rust can easily be removed by soaking the magnetite in a rust-removing solvent (although the natural state is beautiful and unique.)

This is a fascinating rock mineral - I encourage you to study more on it!
