    Magnetite: Meanings, Properties and Powers - The Complete ...

    Magnetite Properties. Magnetite is very easy to recognize because it’s one of the very few gemstones that get attracted to a common magnet. It’s the most magnetic mineral that can be found, hence the name. It’s also known as Lodestone or Magnetic Hematite. It’s black-grey in color, but there are also magnetite stones that are grey and ...
