Fluorite or Green Fluorine. Fluorite is a very spiritually powerful stone. It promotes freedom of thought and provides clarity to the mind.

The color green is associated by us with nature, health and vitality. As the color of the chakras, Green Fluorite most represents the heart chakra.

Similar to quartz, Fluorite has been infused with Earth energy and is a birthing and life supporting stone. If you are pregnant or planning to have a baby, choose Fluorine or Fluorite. This crystal supports health, life and implicitly in the process of bringing a new life into the world.

I recommend charging the Fluorite in sunlight .

Here's a short description I stumbled across on youtube.

"The thermoluminescence and phosphorescence properties both indicate that this crystal is an efficient conductor and transmitter of energy.

How does it work?! Electrons are displaced when disturbed by light/heat, and the luminescent quality is the result of an exchange of electrons within the molecular structure. The release of light is a transfer of energy back to the state in which it entered the crystal. (Law of conservation of energy). So I would say that this quality may be a contributing aspect to the healing properties of fluorite, as it is representative of a transformation of energy into a gentle, well-reasoned form that shows itself in its luminescence." (Mojo Magick youtube)

He also recommends cleaning our space with high vibration stones like Selenite and Obsidian and then placing a Fluorite in that freshly cleaned spot. It will create a forest of spiritual energy that will protect the space and make it difficult for low frequency energies to enter our sphere.
