Lab-Grown Diamond Care: The Complete Guide

Lab-grown diamonds are hard enough to shrug off almost anything, but the 925 sterling silver and rhodium finish around the stone is not — so a lab-grown diamond ring or pendant only stays looking new if the metal gets the same attention as the stone. A short weekly clean with warm water and mild soap, a few habits about when to take a piece off, and an occasional check of the setting cover nearly everything below. This guide walks through all of it, from daily wear to knowing when a stone or prong needs a jeweller’s eye.

Why Lab-Grown Diamonds Still Need a Care Routine

Lab-grown diamonds are chemically and physically identical to mined diamonds — the same carbon, grown under controlled conditions rather than underground, and the same Mohs hardness of 10, the top of the scale. That hardness means the stone itself resists scratching extremely well; it will not wear down or dull the way a softer gemstone can.

Care still matters, for two reasons that have nothing to do with the diamond’s toughness. First, skin oils, lotion, soap residue and everyday dust settle on the stone and its setting, and that buildup is usually what makes a diamond look duller over time — not the stone itself losing anything. Second, every GemsGlitz ring and pendant is set in 925 sterling silver with a rhodium finish (see our materials page for the full breakdown), and both the silver and the plating respond to how a piece is worn, cleaned and exposed to chemicals. A hard stone in a neglected setting still looks tired; a clean, well-kept setting is what lets the diamond read as brilliant.

Daily Habits That Keep Your Jewelry Looking Its Best

Most of what keeps lab-grown diamond jewelry looking new happens before you ever reach for a cleaning cloth. A simple rule covers most of it: put jewelry on last, after makeup, lotion and perfume, and take it off first, before anything that could scratch, coat or chemically expose it.

In practice, that means removing rings and pendants for:

• Swimming or hot tubs — chlorine and other pool chemicals can dull metal and, with repeated exposure, affect a rhodium finish.
• The gym or sports — sweat, friction and impact all add wear, and a ring is easy to catch or knock during exercise.
• Cleaning, dishwashing and gardening — household cleaners, soil and repeated contact with hard surfaces are hard on both the setting and the finish.
• Applying lotion, sunscreen or perfume — these leave a residue that dulls a diamond’s sparkle faster than almost anything else.

Handling a ring by its band rather than the stone, and giving jewelry a quick wipe with a soft cloth after wearing it, are both small habits that add up over months of daily wear.

How to Clean Your Jewelry at Home, Step by Step

A basic clean with warm water and mild soap is enough for most day-to-day buildup on both the diamond and the sterling silver setting.

1. Mix a few drops of mild, unscented dish soap into a bowl of warm — not hot — water.
2. Soak the piece for 15–20 minutes to loosen oils, lotion residue and dust.
3. Gently brush the stone and the setting with a soft-bristled brush (a clean, soft toothbrush works well), paying attention to the underside of the stone and any crevices in the setting, where residue collects.
4. Rinse thoroughly under warm running water so no soap film is left behind.
5. Dry immediately and completely with a soft, lint-free cloth. Don’t let the piece air-dry — trapped moisture is a common cause of tarnish on sterling silver.

For light everyday touch-ups between full cleans, a quick buff with a soft microfiber cloth lifts surface oils without needing a full soak.

For Grime a Basic Clean Doesn’t Shift

If a soap-and-water soak isn’t cutting through built-up residue, repeat the soak for longer rather than reaching for something stronger. Skip baking soda and other pastes on rhodium-finished silver: even a mild abrasive can wear the finish over time, and plain soap, warm water and a soft brush will lift almost any everyday grime. Rinse completely — residue left behind can itself cause dullness.

What to Avoid When Cleaning and Wearing Your Jewelry

A handful of products and habits do more damage than ordinary wear ever will.

• Chlorine and bleach. Both are common in pools, hot tubs and household cleaners, and both can affect sterling silver and a rhodium finish with repeated exposure.
• Ammonia-based and other harsh cleaners. These are too aggressive for regular use on a delicate setting, even where a heavily diluted version is sometimes suggested for other jewelry types.
• Abrasive cloths, paper towels or gritty pastes, including toothpaste. Rhodium is a thin plating, and anything with texture can dull or gradually wear it thin — stick to soft brushes and lint-free cloths.
• Ultrasonic cleaners, used without caution. They’re a common professional tool, but the vibration can work a stone loose in a delicate or closely-set piece, such as a pavé or channel-set band. If you’re not certain a piece is a safe fit for one, a jeweller is better placed to judge than a guess at home.
• Scrubbing hard “to get it really clean.” Dirt lifts with soaking and a soft brush; heavy pressure is more likely to stress a setting than to clean it any faster.

How Often to Clean, Check Settings, and When to See a Jeweller

Cleaning Frequency

There’s no single right interval — it depends on how often a piece is worn. As a general guide, a quick wipe after each wear plus a full soap-and-water clean every one to two weeks keeps daily rings and pendants looking their best; pieces worn only occasionally can go longer between cleans.

Checking Prongs and Settings

Every few weeks, take a moment to look at the setting rather than just the stone. Gently press or wiggle the stone with a fingertip — it should not move at all. A prong-set stone, like a classic solitaire, relies on a small number of prongs holding it in place, so it’s worth checking more often than a bezel setting, which encloses the stone in a continuous rim of metal and typically needs less frequent attention.

When to See a Jeweller

Book a professional check if you notice any movement in the stone, a prong that looks flattened, bent or thinner than the others, a setting that catches on fabric, or a diamond that stays dull after a proper clean. None of these are emergencies, but they’re the kind of small issue that’s far easier to deal with before a stone works loose than after.

Sterling Silver, Rhodium and Tarnish

The metal around a lab-grown diamond needs its own attention, separate from the stone. Sterling silver is a durable, workable alloy, but like all silver it reacts with sulfur compounds in the air over time, which is what causes tarnish — a gradual dulling or yellowing of the surface. The rhodium finish on GemsGlitz pieces adds a bright, reflective layer over the silver and some tarnish resistance, but it’s a plating rather than a permanent seal, so the same habits that protect the diamond — drying thoroughly, avoiding harsh chemicals, keeping pieces away from humid storage — also protect the finish underneath.

If a piece starts to look duller or slightly yellow despite regular cleaning, that’s usually tarnish rather than anything wrong with the diamond. We cover the causes and the fixes in full in how to prevent sterling silver tarnish, and go deeper on why the two materials work well together in sterling silver and lab-grown diamonds: a perfect pairing.

Eco-Friendly and Non-Toxic Cleaning Options

You don’t need a specialist jewelry cleaner or anything harsh to keep lab-grown diamond jewelry looking its best. A few gentle, low-impact options work well:

• Mild, biodegradable dish soap and warm water — the default method above, and the one we’d recommend for regular use.
• A longer soak rather than a stronger product when a piece needs a deeper clean — the same soap and warm water, just more time.
• A soft, reusable cloth instead of disposable wipes, which cuts down on waste without any loss of effectiveness.

Diluted white vinegar is sometimes suggested for jewelry cleaning, but its acidity can affect some metals with repeated or prolonged use, so if you try it, keep the solution mild, limit contact time, and rinse thoroughly afterward. When in doubt, plain soap and water is both the gentlest option and the easiest to get right.

Caring for Rings: Engagement and Everyday Wear

Rings take more daily impact than any other piece of jewelry — hands touch almost everything — so they’re the pieces most worth building a routine around. Remove a ring before chores, exercise or swimming, and check the setting every few weeks rather than only once a year.

Setting style affects what to watch for. A classic solitaire, like our Eternal, holds its stone with a small number of prongs, so it’s worth a periodic wiggle-check. A half-eternity design set with smaller accent stones, like our Celeste band, has more settings close together — exactly the kind of piece where it’s worth skipping a home ultrasonic cleaner in favor of a gentle hand clean. Stacking and eternity bands, such as our slim Aura band, sit close to other rings on the finger, so during cleaning give each band its own gentle pass rather than scrubbing two together, which can dull their edges against each other over time.

Whatever the setting, the same core routine — soap and water, a soft brush, a full dry, and an occasional look at the prongs — covers all of it.

Caring for Pendants and Chains

Pendants and their chains pick up a slightly different mix of residue than rings, since a chain sits against skin and clothing all day and collects body oils and product runoff along its full length, not just at the setting.

The same soap-and-water clean works for both the pendant and the chain: soak, brush gently along the links with a soft toothbrush, rinse, and dry the chain fully before putting it away, since trapped moisture between links is a common spot for tarnish to start. Always fasten the clasp before cleaning or storing a piece, both to keep the chain from catching on the brush and to reduce strain on the clasp mechanism itself.

Whether it’s a solitaire pendant or a more detailed design like our Grace, the setting deserves the same periodic check as a ring — a gentle look for movement in the stone, and attention to the clasp and jump rings, which see more repeated stress than almost any other part of a pendant.

Frequently Asked Questions

How often should I clean my lab-grown diamond ring or pendant?

A quick wipe after each wear and a full soap-and-water clean every one to two weeks is a reasonable routine for a piece worn daily. Jewelry worn only occasionally can go longer between cleans.

Can I use an ultrasonic cleaner on my lab-grown diamond jewelry?

Use caution. Ultrasonic cleaners are a common professional tool, but the vibration can loosen a stone in a delicate or closely-set piece, so a plain soap-and-water clean at home is the safer default. A jeweller is best placed to judge whether a specific piece is a good fit for one.

Will chlorine or swimming pool water damage my jewelry?

Repeated exposure can affect both sterling silver and a rhodium finish, so it’s worth taking rings and pendants off before swimming or using a hot tub rather than relying on cleaning to undo the exposure afterward.

Do lab-grown diamonds need different care from natural diamonds?

No. Lab-grown and natural diamonds share the same chemical composition and the same Mohs hardness of 10, so the same cleaning and care routine applies equally to both.

How do I know if a prong or setting needs attention?

Gently press or wiggle the stone with a fingertip — it shouldn’t move. If it does, or if a prong looks bent, flattened or thinner than the others, it’s time to see a jeweller rather than keep wearing the piece.

Is it safe to clean sterling silver with baking soda or vinegar?

For rhodium-finished pieces like ours, we’d avoid both. Baking soda is mildly abrasive and can wear the rhodium finish over time, and vinegar’s acidity isn’t needed for everyday grime. Warm water, a drop of mild soap and a soft brush are all a GemsGlitz ring or pendant needs.

None of this requires a specialist kit — warm water, mild soap, a soft brush and a few sensible habits about when to take jewelry off cover almost every lab-grown diamond ring and pendant we sell. Pair that routine with the right storage between wears, and a piece bought today should still look the way it does now for years to come.
