How to Care for Lapis Lazuli Jewelry (A Softer, Porous Stone)

By Lisa Chen, Founder · July 1, 2026

Short answer: caring for lapis lazuli is easy once you know the one rule — it is a soft, porous stone, so keep it away from water, chemicals, heat, and rough handling, and clean it with nothing more than a soft, barely damp cloth. Lapis sits at roughly 5 to 6 on the Mohs hardness scale, on the softer end for a stone you wear every day, and because it is porous it can drink in perfume, lotion, sweat, and pool water. That sounds fragile, but it is not: the Gemological Institute of America (GIA) still calls lapis durable enough for daily wear. The trick is knowing what actually harms it, and what is just scare talk.

What lapis lazuli actually is, and why that dictates the care

Here is the thing most care guides skip: lapis lazuli is not one mineral, it is a rock, an aggregate of several minerals pressed together. GIA describes it as a mix of lazurite (which gives lapis its deep, saturated blue), calcite (the white flecks or streaks), and pyrite (the little golden, metallic-looking specks people love). A stone made of one hard, uniform mineral shrugs off a lot. A rock made of several minerals with different hardnesses and chemical sensitivities has more ways to go wrong: the softer calcite reacts to acids, the pyrite can be disturbed by vibration, and the whole aggregate is porous. So when you care for lapis, you are really caring for the weakest link in the mix, not the strongest.

Why soft and porous is the whole story

Two properties do all the work here, so it is worth understanding them rather than just memorizing a rules list.

First, softness. On the Mohs scale, the standard 1-to-10 ranking of scratch resistance, lapis lands around 5 to 6, depending on its exact composition (many sources cite 5 to 6). For comparison, quartz, which is in ordinary household dust, is a 7, harder than lapis. So everyday grit can scratch it, and a harder stone rattling next to it in a jewelry box definitely can. GIA rates its toughness, which is resistance to chipping and is separate from scratch resistance, as only "fair." None of this makes it unwearable; it just means you handle it with a little more awareness than you would a diamond.

Second, porosity. Lapis has tiny openings across its surface, so liquids do not sit on top and roll off the way they would on glass. They get drawn in, along with whatever is dissolved in them. That is why perfume, lotion, chlorinated pool water, and even the salts in sweat are a problem: the stone absorbs them, and over time that can dull the polish or shift the color. It is also why lapis is so commonly dyed to deepen its blue, then sometimes sealed with wax or resin, and a dyed, sealed stone has its own vulnerabilities, which is the next piece.

The one rule that matters most: no ultrasonic, no steam

If you remember nothing else, remember this. GIA is direct about it: clean lapis lazuli with warm, soapy water, and never with steam or ultrasonic cleaners. There are two reasons, and both come straight from what lapis is made of.

An ultrasonic cleaner works by shaking a piece with high-frequency vibration in a liquid bath. On a solid, hard stone that is fine. On a mixed-mineral rock like lapis, that vibration can loosen the seams between the lazurite, calcite, and pyrite that make it an aggregate, and drive liquid deep into the pores. Steam adds heat and pressure, which lapis also dislikes. And if your stone is dyed, and a lot of commercial lapis is, the heat and solvents can make the dye bleed or the wax sealer break down. GIA notes that the dye in some lapis can come off if it is rubbed with acetone or denatured alcohol, and that heat or solvents can damage a treated gem's surface. So the machine that makes your diamond ring sparkle is the one thing to keep your lapis far away from.

How to clean lapis lazuli, step by step

The good news is that the right method is almost boringly gentle. You are wiping, not scrubbing or soaking.

• Wipe after wearing. A quick pass with a soft, dry cotton or microfiber cloth lifts off skin oils, lotion, and dust before they settle into the pores. This one habit prevents most buildup.
• For a real clean, use a barely damp cloth. Dampen a soft cloth with lukewarm water, and only a tiny amount of very mild soap if it is genuinely grimy, then wipe the surface. Do not submerge or soak the stone.
• Wipe the soap off and dry it right away. Follow with a clean, damp cloth to remove any residue, then dry the piece immediately and thoroughly with a soft, dry cloth. Standing moisture is the enemy of a porous stone.
• Never use acids, solvents, or household cleaners. No vinegar, lemon, acetone (nail polish remover), denatured alcohol, or all-purpose spray. The calcite reacts to acids and the dye or sealer can break down from solvents.
• Skip the toothbrush and the jewelry-dip bath. Both are too aggressive for a soft, porous, often-dyed stone.

That is the entire routine. If a piece looks past saving, deeply dull or with a damaged surface, that is a job for a professional jeweler or gem cutter, not a home fix.

What to keep lapis away from (the honest list)

Because the stone absorbs and reacts, the smartest care is mostly about what you do before you put the jewelry on and when you take it off.

• Perfume, cologne, hairspray, and lotion. Apply them first, let them dry, and put your lapis on last. The alcohol in fragrance is especially rough on dyed stones.
• The shower, the sink, and the pool. Take lapis off before you wash your hands for long, shower, do dishes, or swim. Prolonged water exposure seeps into the pores, and pool chlorine slowly erodes the polish.
• Sweat and heavy activity. Remove it before a workout or a hot day of hard work. The salts in sweat get absorbed just like anything else.
• Heat and direct sunlight. Do not leave lapis baking on a sunny windowsill or wear it in a sauna. Prolonged heat and strong sun can fade the blue over time.
• Rough storage. Store each lapis piece on its own, in a soft pouch or a lined, separate compartment, so a harder stone or a chain clasp cannot scratch it.

Tough setting, delicate stone: why the metal is not the weak point

Here is a distinction that clears up a lot of confusion. When a lapis piece is set in the right metal, the setting is often far tougher than the stone. Our own lapis pieces, for example, are built on a 316L stainless steel base with an 18k gold-plated finish, made to resist tarnish and shrug off water and sweat. The steel band under the gold is genuinely hard-wearing. But a tough setting does not make the stone tough. The steel can handle a splash the lapis cannot, so even on a waterproof, tarnish-free setting you still follow the stone's rules, not the metal's: the piece is only as water-shy and scratch-shy as the softest thing in it, which is the lapis. Think of it as a durable frame around a delicate painting. The frame protects the painting; it does not turn it into something you can hose down.

Do not fearmonger yourself out of wearing it

It is easy to read a care list like this and decide lapis is too precious to actually enjoy. It is not. GIA, the same authority telling you to keep it out of the ultrasonic, also states plainly that lapis is durable enough for daily wear, and that with care, lapis jewelry can delight its owners for generations. The realistic bar is simple: treat it like a nice leather bag, not a raw egg. You would not throw a leather bag in the washing machine, but you would carry it every day without a second thought. Put your lapis on after your perfume, take it off before the shower, wipe it now and then, and store it so nothing scratches it. Do that and the stone will outlast the trend that made you buy it.

Frequently asked questions

Can lapis lazuli get wet?

A quick, brief splash will not instantly ruin it, but you should not let lapis sit in water. Because the stone is porous, prolonged contact lets water and anything dissolved in it soak into the pores, which can dull the polish and, on dyed stones, disturb the color. Take lapis off before showering, swimming, doing dishes, or long hand-washing, and dry it right away if it does get wet.

Can I clean lapis lazuli in an ultrasonic or steam cleaner?

No. GIA advises cleaning lapis with warm, soapy water and never with steam or ultrasonic cleaners. The vibration can loosen the different minerals in the rock and drive liquid into the pores, and the heat and solvents can make any dye bleed or a wax sealer break down. Use a soft, barely damp cloth instead.

Does lapis lazuli scratch easily?

More easily than a hard stone, yes. Lapis sits around 5 to 6 on the Mohs hardness scale, and everyday dust contains quartz at 7, which is harder. It will not fall apart, but it can pick up scratches over time from grit or from harder jewelry rubbing against it. Storing each piece separately in a soft pouch is the simplest way to prevent that.

Is my lapis lazuli dyed, and does that change how I care for it?

Quite possibly. Because natural lapis is porous, it is very commonly dyed to deepen the blue, then sometimes sealed with wax or resin. Dyed lapis is more sensitive to solvents: acetone (nail polish remover) and denatured alcohol can pull the dye out, and heat can break down the sealer. Since you usually cannot tell by looking, care for all lapis as if it were dyed: no solvents, no heat, no ultrasonic.

How do I store lapis lazuli jewelry?

Keep it dry and keep it apart. Store each lapis piece in its own soft pouch or a lined, separate compartment of your jewelry box so a harder stone or a metal clasp cannot scratch it. Avoid a spot that gets direct sun or heat, since prolonged exposure can fade the blue.

The one rule to carry with you: lapis is a soft, porous stone in an often-tough setting, so you care for the stone, not the metal, with a gentle wipe, no water, no chemicals, stored on its own.
