How to care for Smoky quartz

  • Moonlight: In tradition, stones are left in moonlight overnight, especially around the full moon.
  • Sound: In tradition, a bell or a singing bowl is rung near the stone.
  • Running water: Rinse briefly under running water and dry with a soft cloth.
  • Smoky quartz can fade in sunlight; keep it out of direct sun.
  • Sunlight cleansing is not suggested for any stone: many fade, and a missing record does not mean a stone is sun-safe.
  • Salt is not suggested: it can harm porous and soft stones.
