Selenite is my most favorite because of its propertie to expand and move light energy! A set like this can be placed along the major meridian lines of the body to clrify, and make the flow of energy more effieient as well as to clear out small blockages that occur along the meridian points. You can also set intentions and make an array of these wands to focus the energy of your intention into creation more efficiently. There re relally no limits to wht you can do with the combination of selenite and light energy. If you want none of that, just having selenite in your environment is calming.
