These are flat(ish) and would work well as a charging base, or as an addition to your altar, grid, or other crystal groupings. You can use these under your massage/Reiki table for a little extra help shifting the energies as well. These are NOT perfectly smooth or even, as you can see, but crystals will sit nicely on top of them. (I tested them ;)
Selenite assists with mental clarity, and expanding awareness of self and surroundings. It opens and activates the crown and higher crown/ascension chakras, allowing access to higher dimensional energies and guidance. During meditation, selenite can be used to access past and future lives (keep in mind that future lives are only showing the probable outcome if the current path is followed. If you make a different choice or follow another path, it will change). Selenite helps to anchor the light body to the earth's vibration. It is a very calming stone that instills peace and calms the mind. Selenite helps you to see things from all sides, revealing the deeper meaning and seeing through facades, enabling you to make clearer decisions. This is a fabulous healing crystal!!! Selenite helps to shift the energies quickly, breaking up the stuck and stagnant energies and letting Divine energies flow. It cleanses, charges, amplifies and raises the vibration of any crystals placed with it, plus it is a self-cleaning crystal!
