Crystal Hardness Reference — What's Water-Safe, What's Sun-Safe
Mohs hardness scale of common healing crystals, plus which can be cleansed in water and which can't.
△
The Mohs scale measures scratch resistance from 1 (talc, softest) to 10 (diamond, hardest). It tells you what survives water, salt, and rough handling. Below, every crystal in the Agni Crystals catalogue with its hardness and care notes.
Hard (6.5–7+) — water-safe
Medium (5–6) — gentle care
Hematite (5.5–6.5), Sodalite (5.5–6), Lapis Lazuli (5–6 — but contains calcite which dissolves), Moonstone (6), Rainbow Moonstone (6), Labradorite (6), Sunstone (6.5), Amazonite (6), Howlite (3.5 — soft, despite white look). Quick rinses only; avoid prolonged water.
Soft (2–4) — never water, smoke only
Selenite (2) literally dissolves in water. Malachite (3.5) creates toxic dust if abraded — never sand, never wet. Lepidolite (2.5–3.5) flakes apart in water. Stichtite (2.5) too soft. Cleanse these with smoke (sage, palo santo, camphor) only.
Iron-rich — sun OK, water risky
Pyrite (6–6.5), Hematite (5.5–6.5), Black Tourmaline (7) — these can take direct morning sun. Pyrite and hematite rust if wet — use smoke only.
Coloured — sun fades them
Amethyst, Rose Quartz, Citrine, Fluorite, Multi-Fluorite, Stichtite, Rainbow Obsidian — direct sun fades the colour, sometimes within hours. Use moonlight for cleansing instead.
Quick rule: If you don't know your crystal's hardness, use smoke. Smoke is universally safe. Water is great for quartz family but disastrous for soft and iron-rich crystals. Sun is risky for coloured crystals always.
