The short version: a display guide — where crystals tend to look good and hold up well around the house.
Entry — a black tourmaline or amethyst cluster on a console makes a strong first note.
Living room — larger statement pieces: a citrine or amethyst geode, a polished sphere on a stand.
Bedroom — softer tones suit the nightstand: rose quartz, a selenite lamp (keep it away from humidity).
Office / desk — smaller stones within reach: tiger eye, pyrite, clear quartz points.
Bathroom — mind the moisture: choose hard quartz-family stones, and keep selenite and other soluble minerals out.
