Smithsonite is a fairly hard Zinc Carbonate. The pure form is white, it also forms beautiful blues and rarely a pink purple.
Metaphysically Smithsonite has a very soothing energy as shown by the flowing forms the crystal takes. This soothing calming healing energy invokes angelic guidance. Blues will work more with emotions and expression, whites more with mental stress, and this unusual pink purple takes the pressure off love and relationships.
When you are calm, tranquil, peaceful - good things happen !
