How to Clean & Care for Obsidian Daily

Why clean obsidian?

Worn regularly, a stone gradually picks up invisible traces: skin oils, dust, residue from lotions or perfume. Nothing harmful, but obsidian's deep black loses some shine. Gentle, regular cleaning restores its brilliance.

Note: we're talking about physical cleaning here—caring for the stone and jewelry. Energetic cleansing, from crystal healing practice, is a separate topic. For that, see my article on cleansing and charging.

The right method

Simplicity is safety:

• wipe the stone with a soft cloth (microfiber), dry or slightly damp;
• if needed, use a bit of warm water with a drop of gentle soap, then rinse briefly;
• for tight spaces (beads, prongs), a soft-bristled brush works wonderfully;
• dry thoroughly with a clean cloth, leaving no moisture behind.

That's all. Obsidian needs no special product: gentleness beats quantity.

What to avoid

Obsidian is volcanic glass: beautiful, but medium-hardness (roughly 5 to 5.5 on Mohs) and sensitive to impacts. A few pitfalls to sidestep:

• Salt and salt water: can dull and damage the stone over time;
• harsh cleaners: detergents, alcohol, ammonia, toothpaste, or scouring pads;
• ultrasonic cleaners and steam: unsafe for this kind of glass;
• impacts and scratches: avoid bumping it or storing with harder stones;
• prolonged sunlight and heat: unnecessary, and sometimes harmful to settings and threads;
• long soakings: a quick rinse always suffices.

Smart habit: remove jewelry before showering, swimming, housework, exercise, or bed.

Preserving shine and settings

Beyond the stone, the setting often needs attention. For a pendant or ring, the right cloth for the metal restores the whole piece. For a bracelet on elastic thread, the thread is the most fragile part: water, soap, lotion, and perfume wear it prematurely.

So keep the thread dry, avoid wearing the bracelet right after applying lotion, and don't hesitate to have it restrung if it loosens over time: the stone remains perfect and can be remounted without issue.

How to store obsidian

Since obsidian scratches easily, store it separately, in a soft pouch or a padded compartment, away from harder stones (quartz, topaz) and jewelry that might mark it.

Avoid hot, humid places or direct sunlight. A jewelry box kept in dim light is ideal for keeping it flawless between wears.

How often?

There's no strict rule. Cleaning now and then works fine: when the stone looks dull, after wearing it heavily, or whenever you feel drawn to care for it. Consistency and gentleness matter more than frequency.

And energetic cleansing?

In crystal healing, we distinguish physical cleaning (this page) from cleansing and charging the stone's energy, which is a separate practice. If that interests you, I explain it in detail—smudging, moonlight, amethyst—in my cleansing and charging guide.
