This can be used to make a wonderful gift by adding some crystals, sage or candles in a pretty box. Or for yourself to make a crystal charging grid. There are many uses. Selenite charging plates are hand made in morocco so they are not perfectly round and size my vary by .5" smaller or larger. The thickness can also vary. It is a calming stone and is excellent for meditation or spiritual work. It assists judgment and insight. It clears confusion and aids in seeing the deeper picture. Great for cleaning and charging your crystals. Spiritual activation; communion with Higher Self, spirit guides and angels. Selenite is also a stone of truth and honesty. This promotes good business practices as well as honesty in other types of relationships. Selenite cannot be cleansed in water as it will begin to dissolve. It is also best not to keep it in the bathroom or kitchen near water for the same reason. If you have questions or concerns feel free to send a message and I will respond as soon as I can.
