Jade is a very hard stone of long life. We use two kinds: the one traditionally called "Mayan jade", an opaque green, and white jade that can be tinted with multiple colors. It represents honesty, especially in all aspects related to power. It allows to give objectivity to the judgment of others and to confront the realities. On a physical level, it would be beneficial for fever and migraines. It would also treat dizziness and dysfunctions of nervous origin such as shingles or eczema.
