Start dry
A soft microfiber or glasses cloth removes most everyday dust and fingerprints without any water. Avoid paper towels — the wood fibers are coarse enough to leave micro-scratches on polished surfaces over time. For jewelry, wipe in one direction along the setting, not in circles.
Which stones can touch water
The quartz family — clear quartz, amethyst, rose quartz, citrine — is fine with lukewarm water and a drop of mild soap. So are agate, jasper and garnet. Avoid water for selenite, malachite, azurite, calcite and all salt stones: they dissolve, dull or change color when wet. When in doubt, dry-clean only. Where the hazard goes beyond the surface finish, the water safety guide covers which stones should stay out of drinking water entirely.
Jewelry needs extra attention
If the stone is set in silver, clean the metal separately with a silver polishing cloth — silver tarnish will not come off with soap. Do not soak jewelry for more than a minute; water gets into settings and loosens them over time. For tight corners, wrap a toothpick in a soft cloth and clean gently.
Never reach for these
Ultrasonic cleaners (they shake apart fractured and pale stones), steam cleaners, bleach, toothpaste and hard-bristle brushes. Toothpaste is the sneaky one — it contains abrasives that remove polish. If a stone is genuinely dirty beyond a gentle wipe, a jeweler's professional clean is the safer route than anything you can do at home.
Drying and finishing
After any water contact, pat dry with a soft cloth immediately — do not let the piece air-dry on a towel, and never dry it in sunlight. Water spots are easier to prevent than to remove. Once dry, a quick buff with the microfiber cloth brings back the shine. Store pieces separately so they do not knock together; more on that in our storage guide.
Water tolerance, by stone family
The single most useful rule in crystal care is knowing whether your stone can touch water. Three groups cover most of what people own, and sorting a piece into the right group takes one glance at the label.
| Group | Stones | How to clean |
|---|---|---|
| Water-safe | Clear quartz, amethyst, rose quartz, citrine, agate, jasper, garnet | Lukewarm water, one drop of mild soap, pat dry |
| Brief contact only | Turquoise, opal, lapis lazuli | Damp cloth, dry immediately, never soak |
| Dry only | Selenite, calcite, malachite, azurite | Soft dry cloth or a soft brush, no water at all |
Step by step, for a stone that is actually dirty
Most stones only need a wipe. When one has real grime on it - a bracelet worn all summer, a pendant that has been in a pocket - work through these steps in order and stop as soon as the stone looks clean.
- Start with a dry soft cloth and take off surface dust first
- Mix lukewarm water with a single drop of mild soap, not detergent
- Use a soft baby toothbrush only on raw or unpolished surfaces
- Rinse under running water for a few seconds rather than soaking
- Pat dry immediately with a lint-free cloth, then buff lightly
- Finish by checking the drill holes and the space under the prongs
Where dirt actually hides
Most grime is not on the face of the stone. It collects in three places: inside the drill holes of beads, in the gap between a stone and its setting, and in the elastic between beads on a bracelet. A cloth never reaches any of them. A dry soft brush or a toothpick wrapped in cloth handles the first two. For elastic strands, wipe between the beads one at a time with a barely damp cloth and dry as you go, so no water sits against the cord.
Tarnish is a metal problem, not a stone problem
Silver darkens; the stone does not. Clean the metal with a silver polishing cloth and keep that cloth away from porous stones, because the polish can work into the surface. Silver dip acts faster but should not touch turquoise, opal, pearl or anything with a surface treatment. Gold-plated pieces need the gentlest handling of all - abrasive polish takes the plating off along with the tarnish, and the plating does not come back.
How often is enough
Daily-wear jewelry: a dry wipe once a week and a proper water clean once a month. Display pieces: dust monthly with a dry cloth and otherwise leave them alone. Raw and unpolished specimens: a soft dry brush every few months. Cleaning more often than that does not protect a stone, it just adds more chances to drop it on a hard floor.
Three mistakes that look like cleaning
Toothpaste is an abrasive rather than a cleaner, and it dulls polish on exactly the stones you care about most. Paper towels leave micro-scratches on polished surfaces over months of use, which is why the cloth matters as much as the technique. And leaving a bracelet to air-dry lets water sit in the drill holes, where it weakens elastic and leaves spots. Each of these does more harm than the dirt it was meant to remove.
Storing clean: the overlap worth knowing
Cleaning and storing are the same job done at different times. A stone that has just been cleaned and then dropped into a drawer with harder stones comes out scratched, and a scratch can look like dirt until you look closely. Keep one pouch per stone, store by hardness, and put jewelry on last when you are getting dressed. Our storage guide covers the box itself and the materials to avoid.
How to clean a piece you cannot identify
Second-hand pieces and inherited jewelry often arrive without a name. Treat an unknown stone as water-sensitive until proven otherwise: dry cloth first, then a soft brush for crevices, and stop there. If a damp cloth is not enough to lift the grime, test a hidden spot - the back of a pendant or the inside of a bracelet - and check for dulling or color lifting before you clean the visible side. A photograph in daylight plus the original listing is often enough for a seller or a jeweler to name the stone, and knowing the name is what makes every later decision easier.
