Octahedrons relate to the element of air: a mobile and changeable force, powerful and catalytic, and these shaped crystals can be utilised to bring out these attributes at times of change. Fluorite is an unusual stone in that some of its family members fluoresce under UV light. This shows that it is capable of working at "hidden" levels on a much Higher vibration than might be seemingly occurring.
