How to understand it
Identify the material before repeating a claim about it. Amethyst and citrine are varieties of quartz, while moonstone belongs to feldspar; a trade name may hide treatment or even a different material.
An example
A useful practice is visual and reflective: choose a color or texture that reminds you of a value, then write the action that value calls for. The action does the work.
Use it carefully
For purchases, ask about identification, treatments and provenance. For health concerns, use qualified care rather than a stone.
Try a reflection
What concrete action does this object remind you to take?
