• Rose Quartz
• Citrine
• Smoky Quartz
• Carnelian
• Tiger's Eye
• Jasper
• Aventurine

How to Tell if a Crystal is Water-Safe

  • Check Mohs hardness scale: 6+ is generally safe, below 6 is risky
  • Avoid crystals ending in "-ite" (often soft: selenite, calcite, fluorite)
  • Never use water on metallic crystals (pyrite, hematite, galena)
  • Copper-based stones (malachite, azurite, chrysocolla) can be toxic when wet
  • When unsure, use moonlight, smoke, or sound instead

Sunlight Safety

Which crystals fade or get damaged in sun

✓ Sun-Safe Crystals

• Clear Quartz
• Smoky Quartz
• Black Tourmaline
• Obsidian
• Carnelian
• Red Jasper
• Tiger's Eye
• Hematite
• Agate
• Pyrite
• Onyx
• Garnet

✗ Will Fade in Sun

• Amethystfades to pale
• Rose Quartzloses pink color
• Aquamarinefades quickly
• Fluoritecolor loss
• Celestitefades quickly
• Kunzitevery sensitive
• Opalcan crack
• Turquoisefades & dries
• Aventurinecolor fades
• Citrine (natural)pales

Sun Exposure Guidelines

  • Limit sun-safe crystals to 2-4 hours maximum
  • Morning or late afternoon sun is gentler than harsh midday
  • Color fading from sun is PERMANENT and irreversible
  • Heat from direct sun can crack certain crystals (opal, celestite)
  • When uncertain, use moonlight - it's safe for ALL crystals

Salt Safety

Which crystals can handle salt cleansing

✓ Salt-Safe Crystals

Hard, non-porous stones (Mohs 7+)

• Clear Quartz
• Amethyst
• Citrine
• Smoky Quartz
• Rose Quartz
• Carnelian
• Jasper
• Obsidian

✗ Avoid Salt

Soft, porous, or metallic stones

• Selenite - dissolves
• Calcite - corrodes
• Hematite - rusts
• Pyrite - corrodes
• Fluorite - damaged
• Malachite - damaged
• Opal - dries out
• Turquoise - damaged

Potentially Toxic Crystals

Handle with care - toxic when wet, broken, or ingested

High Risk Crystals

Malachite
Contains copper - toxic when wet or powdered
Cinnabar
Contains mercury - highly toxic
Galena
Contains lead - toxic if inhaled or ingested
Chrysocolla
Contains copper - avoid in water
Azurite
Contains copper - toxic when wet

Safety Guidelines

  • NEVER make crystal elixirs with these stones
  • Wash hands thoroughly after handling
  • Keep away from children and pets
  • Never use in direct contact with water
  • Safe for external use when intact
  • Use moonlight or smoke for cleansing
