Metaphysical.

In philosophy, metaphysics is the branch concerned with the nature of reality beyond the physical: causation, identity, time, mind. In crystal and wellness contexts, metaphysical has drifted into a much narrower use. It is the umbrella label for the modern tradition of associating stones with feelings, intentions, chakras, planets, and outcomes. When a listing speaks of a stone's "metaphysical properties," it is referring to this body of practice rather than to anything established in the laboratory.

The tradition itself is a layered inheritance. Strands come from medieval European lapidaries, Hindu and Buddhist sources via the chakra system, Theosophy, the New Age movement of the 1970s and 1980s, and the contemporary crystal community online. Different sources disagree, sometimes sharply, about what a given stone "does."

The honest framing is that metaphysical claims are not scientific claims. They can still be useful, in the way that any well-worn vocabulary can give shape to inner experience. A buyer who treats metaphysical descriptions as suggestions rather than diagnoses tends to get the most out of them.
