How to Care for Diamond Jewellery — The Definitive Guide for 2026 (Lab Grown & Natural)

You spent weeks choosing it. Maybe months saving for it. And then it quietly ended up next to the hand soap, getting clouded by lotions and losing its fire under a film of everyday life. It happens to the best of us. 

Whether you're wearing a classic natural solitaire or a stunning lab grown diamond piece, the care principles are largely the same — but there are a few nuances worth knowing. With the lab grown diamond market growing rapidly (the global lab grown diamond jewellery market was valued at over USD 24 billion in 2024 and continues to expand through 2026), more buyers than ever are asking: does a lab grown diamond need different care than a mined one? 

The short answer is no. And the longer answer is what this guide is for. 

Lab Grown Diamonds vs. Natural Diamonds: Are They Chemically Different? 

This is the first question anyone should ask before diving into care routines, because the answer shapes everything. 

Lab grown diamonds — sometimes abbreviated as LAO lab grown diamonds in trade terminology — are real diamonds. Chemically, physically, and optically, they are identical to natural diamonds. Both are pure carbon atoms arranged in a cubic crystal structure. Both score a 10 on the Mohs hardness scale, the highest possible rating for a gemstone. The Gemological Institute of America (GIA) and the International Gemological Institute (IGI) both certify lab grown diamonds using the same grading criteria — cut, colour, clarity, and carat — as natural stones. 

What differs is origin, not composition. A lab grown diamond grows in a controlled environment over weeks; a natural diamond forms deep within the earth over billions of years. But once that diamond is set into a ring or pendant, the care it requires is identical. 

Daily Habits That Protect Your Diamond Jewellery 

Remove Before You Reach For These 

This might sound obvious, but the single greatest threat to diamond jewellery isn't impact — it's chemical exposure from everyday products. 

Remove your diamond jewellery before: 

Applying hand cream, sunscreen, or body lotion 

Washing dishes or cleaning the house (bleach and ammonia-based cleaners can pit metal settings over time) 

Swimming — chlorine in pools is particularly damaging to gold alloys 

Exercising or playing contact sport 

Applying perfume or hairspray (always put jewellery on last) 

The diamond itself won't dissolve. But the gold, platinum, or silver setting absolutely can degrade, and a loose prong means a lost stone. 

The Lotions-and-Diamonds Problem 

Oils and lotions are the primary reason diamonds go dull. A diamond's brilliance depends on light passing cleanly through the stone and bouncing back. A thin layer of product residue on the surface doesn't scratch the diamond — it just suffocates its sparkle. This is easily fixed, but even more easily prevented. 

How to Clean Diamond Jewellery at Home 

The Gold Standard: Warm Water, Dish Soap, and a Soft Brush 

Professional jewellers have a simple at-home recommendation that hasn't changed in decades because it works: 

Fill a small bowl with warm (not hot) water. 

Add a few drops of mild dish soap — something gentle, without moisturisers or antibacterial agents. 

Soak your piece for 20–30 minutes. 

Use a soft-bristled toothbrush (a baby toothbrush is ideal) to gently scrub around the setting and beneath the stone. 

Rinse under warm running water — keep the drain plugged or hold pieces over a second bowl. 

Pat dry with a lint-free cloth. Air dry completely before storing. 

Do this once a week for rings you wear daily, and once a month for pieces worn occasionally. 

What About Ultrasonic Cleaners? 

Ultrasonic cleaners — the devices that use high-frequency sound waves to vibrate away grime — are popular and genuinely effective. However, they're not risk-free. They can loosen stones if a setting has existing wear or micro-fractures in the metal, and they're not suitable for diamonds with significant inclusions or fracture-filled stones. 

For well-made, solid pieces in good condition, occasional ultrasonic cleaning is fine. If you're unsure about your setting's integrity, stick to the soap-and-brush method until a jeweller has inspected it. 

What to Avoid 

Toothpaste — abrasive, and it can scratch the metal setting even if it can't scratch the diamond. 

Baking soda paste — same issue. 

Acetone or alcohol on coloured stones — if your piece combines diamonds with rubies, emeralds, or sapphires, some treatments on those stones can be damaged by solvents. 

Paper towels or rough cloths — surprisingly abrasive on polished metal surfaces. 

Storing Diamond Jewellery: The Details Matter 

Diamonds are the hardest natural material on earth, but they can scratch other gemstones — and, given the right angle, they can even scratch each other. Storage is less about protecting the diamond and more about protecting everything around it. 

Best Practices for Storage 

Store pieces individually — each in its own compartment, pouch, or small zip-lock bag. Never toss jewellery into a pile. 

Use a fabric-lined jewellery box — velvet or microfibre lining absorbs light impacts and prevents metal-on-metal abrasion. 

Keep away from direct sunlight — prolonged UV exposure won't damage a diamond, but it can fade treated metals and certain gemstone enhancements over time. 

Maintain moderate humidity — extreme dryness or moisture can affect the metal components of your settings. 

Travel safely — invest in a small, hard-shell jewellery case for travel. Loose pieces in a bag pocket or makeup bag is how stones get lost. 

Professional Maintenance: What You Can't Do at Home 

Annual Inspection Is Non-Negotiable 

Even if your jewellery looks perfect, an annual check with a qualified jeweller is worth every penny. A trained eye — particularly under magnification — can spot: 

Worn or bent prongs before they fail 

Hairline fractures in settings 

Loose stones that haven't yet fallen out 

Thinning of metal shanks on rings worn daily 

Prong re-tipping (restoring worn prong tips) is a relatively affordable repair. Replacing a lost diamond is not. Prevention is straightforward; recovery is expensive. 

Professional Cleaning vs. At-Home Cleaning 

A professional clean uses professional-grade ultrasonic equipment, steam, and a jeweller's eye to assess the piece before and after. It's not just about cleaning — it's an inspection opportunity. Most reputable jewellers offer complimentary cleaning with annual purchases. Brands like Keian Luxandor, known for their precision-crafted lab grown and natural diamond collections, offer aftercare services as a standard part of the ownership experience — a detail worth asking about at the time of purchase with any fine jewellery brand. 

Expert Insights: What Industry Professionals Say 

We asked gemologists and bench jewellers for their most overlooked care tip. The consistent answer? The sink is where most rings die. 

Not dropped. Not scratched. Lost. A ring slipped off during hand-washing, grabbed an engagement ring while doing dishes, or — the classic — set it on the edge of the basin "just for a moment." The number of diamonds that end up in drains every year is genuinely staggering to anyone who works in jewellery repair. 

A secondary insight: lab grown diamond jewellery is not cheaper to repair. The stone itself may have cost less than a comparable natural diamond, but the setting — whether platinum, 18k gold, or silver — is valued identically. The labour of a skilled bench jeweller doesn't change based on a stone's origin. This is worth remembering when deciding how carefully to treat your piece. 

Common Mistakes to Avoid 

1. Wearing diamond rings to the gym. Kettlebells, barbells, and grip-heavy exercise can bend prongs, distort ring shanks, and cause impact damage to settings. 

2. Assuming "hard" means "indestructible." A diamond won't scratch, but it can chip if struck at a precise angle against another diamond or a hard surface. This is rare but real. 

3. Skipping the insurance conversation. Fine jewellery — particularly engagement rings and heirloom pieces — should be appraised and insured. Lab grown diamonds should be valued at replacement cost, not resale value, which differs meaningfully. 

4. Using the wrong cleaner on the wrong metal. Ammonia-based cleaners are fine on platinum but can damage the rhodium plating on white gold over time. Know your metal. 

5. Cleaning in the sink without a stopper. Enough said. 

Lab Grown Diamond Care: Any Differences Worth Knowing? 

Since we're addressing LAO lab grown diamond and diamond jewellery specifically, let's be precise. 

No, lab grown diamonds don't require different cleaning. The same warm water and mild soap method works perfectly. The same storage principles apply. 

However, there is one nuance: some early CVD (Chemical Vapour Deposition) lab grown diamonds occasionally showed slight colour tints under certain lighting conditions, which has led some owners to ask whether their stone is "changing." It isn't — this is simply the stone's inherent colour characteristics. Proper lighting and a clean surface resolve most visual concerns. 

One area where lab grown diamond buyers sometimes have a different experience is certification and documentation. Ensure your lab grown diamond comes with a certificate from a recognised laboratory (GIA, IGI, or GCAL are the most respected). Store that certificate safely — it's as important as the jewellery itself for insurance, resale, and authentication purposes. 

Caring for Diamond Jewellery by Metal Type 

Metal 

Key Care Notes 

Platinum 

Most durable setting metal. Develops a patina over time — can be re-polished professionally. Safe with most cleaners. 

18k Gold (Yellow or Rose) 

Avoid abrasives. Safe for soap-and-water cleaning. Re-polish periodically. 

White Gold 

Often rhodium-plated. Plating wears off over 1–3 years and requires re-plating. Avoid ammonia. 

Sterling Silver 

Tarnishes. Store in anti-tarnish cloth. Polish with silver cloth. Avoid water contact when possible. 

Future Trends in Diamond Jewellery Care (2026 and Beyond) 

The jewellery industry is embracing technology in its aftercare offerings. A few developments worth watching: 

Smart home ultrasonic cleaners are becoming more affordable and consumer-grade, with some now featuring automatic cycle controls that prevent over-cleaning. 

Lab grown diamond traceability via blockchain is expanding — some brands can now verify a stone's full origin chain, which matters for resale and authentication. 

Biodegradable jewellery cleaning solutions are entering the market, replacing petroleum-based formulas with plant-derived surfactants that are equally effective and gentler on metal finishes. 

Wearable jewellery tracking — microchip embedding in settings — is early-stage but gaining traction for high-value pieces. 

Brands that offer transparent aftercare policies, clear documentation, and accessible professional services will increasingly differentiate themselves. For buyers of both natural and lab grown diamond jewellery, aftercare commitment is becoming as important a purchasing criterion as design. 

Conclusion: A Diamond That's Cared for Lasts a Lifetime — and Beyond 

Diamonds have always carried a sense of permanence. The category's emotional weight — milestones, commitments, celebrations — is precisely why they deserve more than neglect. A few minutes of maintenance per week, an annual jeweller visit, and sensible storage habits are genuinely all it takes to keep a diamond brilliant across decades. 

Whether your piece is a natural stone passed down through generations or a precision-grown lab diamond from a brand like Keian Luxandor that represents the best of modern craftsmanship, the care commitment is the same: small, consistent, and entirely worth it. 

The brilliance is built in. Keeping it there is up to you.
