Built to Last: Why Care Is Part of the Commitment
Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds. Their care requirements are exactly the same. There is no separate rulebook.
As of 2026, lab-grown stones now represent the majority of center stones in new U.S. engagement rings, a generational shift toward pieces chosen with intention and built to endure. Care is not maintenance; it is an extension of that intention.
Different metals and stones in the same jewelry wardrobe require different handling. This guide separates each clearly: by material tier, by stone, by what to do and what to avoid. Caring for fine jewelry is simple when you know what you are working with.
The Universal Cleaning Method (Works for Every Piece)
One method covers every piece in your collection as a reliable baseline. No specialist products needed.
- Soak your piece in lukewarm water with a few drops of mild dish soap for 15 to 30 minutes. Lukewarm, not hot. Hot water can stress certain metal settings and affect gemstone treatments.
- Brush gently with a soft-bristled toothbrush, working around prongs, bezels, and the underside of stones where oils and residue collect.
- Rinse thoroughly under lukewarm running water. Make sure no soap film remains.
- Pat dry with a lint-free microfiber cloth. Let the cloth absorb moisture rather than drag across the surface.
This method is appropriate for solid gold and securely set, water-safe gemstones. For rhodium-plated or 22K gold-plated S925 pieces, do not soak for 15 to 30 minutes: use a soft, slightly damp cloth, dry immediately, and follow the finish-specific guidance below.
Rhodium-Plated S925 Sterling Silver: Daily Wear, Handled Right
S925 sterling silver is 92.5% pure silver alloyed with 7.5% copper. That copper content is what makes unplated sterling susceptible to tarnish. The mechanism is straightforward: sulfur compounds in the air and on skin react with the silver and copper to form silver sulfide and copper sulfide, producing the familiar darkening.
DHARIN’s silver-tone S925 pieces use approximately 0.05 μm of rhodium electroplating, followed by a vacuum-applied nano protective coating. The rhodium creates the bright white surface, while the nano layer provides an additional barrier against everyday exposure. Both are surface treatments and will gradually wear with friction.
Selected gold-tone cultivated-gemstone pieces use approximately 0.05 μm of 22K gold electroplating over S925 sterling silver, followed by the same type of vacuum-applied nano protective coating. These pieces are gold-plated sterling silver, not gold vermeil.
Because of the rhodium plating, standard silver-cleaning products are destructive, not helpful. Three common mistakes to avoid:
- Silver dip or liquid silver cleaner: These solutions are formulated for solid, unplated sterling. On rhodium-plated pieces, they strip or degrade the protective layer.
- Silver polishing cloths: These cloths are chemically impregnated and mildly abrasive. They work by removing the top layer of metal. On plated jewelry, that top layer is the plating itself.
- Toothpaste: Toothpaste ranks approximately 3 to 4 on the Mohs Scale of Hardness. Gold and silver both sit around 2.5 to 3. Toothpaste is abrasive enough to scratch both metals, and it can harden beneath gemstone settings, becoming extremely difficult to remove without risking damage.
Finish life varies with friction, moisture, chemicals, skin contact and care; a thickness measurement alone cannot predict a fixed number of years. For rhodium-plated or 22K gold-plated S925 pieces, avoid prolonged soaking. Wipe with a soft, slightly damp cloth when needed, dry immediately, and store separately.
14K Solid Gold: Low Maintenance, High Longevity
14K gold is 58.3% pure gold alloyed with other metals. In yellow and rose gold, this alloy composition produces naturally warm tones without any plating required.
DHARIN's 14K white gold is not rhodium-plated. Its color comes from the alloy composition itself, using palladium and white metal alloys to achieve a naturally refined, slightly warm-white tone. Most white gold sold across the industry relies on rhodium plating (a layer typically just 0.5 to 2.5 microns thick) for its bright white appearance. Without that plating layer, DHARIN's white gold has no coating to strip, wear through, or re-apply.
This distinction matters for care. The universal warm soapy water method applies without additional restriction. There is no plating to protect.
14K solid gold is the most durable of DHARIN's three material tiers for daily wear. It does not tarnish and resists most common chemical exposures. That said, avoid prolonged contact with chlorine (pools, hot tubs), harsh household cleaners, and high-concentration skincare actives such as AHA serums, retinol, and SPF. These accelerate surface wear on any metal over time.
For routine cleaning, the universal method is fully appropriate. Ultrasonic cleaners are safe for plain gold settings, but use caution when stones are present. Defer to the stone-specific guidance below.
Stone-by-Stone: Lab-Grown Diamond, Sapphire, Ruby, and Emerald
Lab-Grown Diamonds (Mohs 10)
The hardest material in your jewelry wardrobe. Lab-grown diamonds are highly resistant to scratching and perfectly suited to the universal cleaning method. One precaution: store diamond pieces separately. Diamonds can scratch softer metals and stones they come into contact with.
Lab-Grown Sapphires and Rubies (Mohs 9)
Extremely durable. Warm soapy water and a soft brush are ideal for routine care. Ultrasonic and steam cleaners are generally safe when stones are securely set and untreated. Lab-grown sapphires and rubies typically have fewer inclusions than their mined equivalents, because they form in controlled environments. This makes them good candidates for mechanical cleaning, though a visual check of the setting beforehand is always wise.
Lab-Grown Emeralds
Emeralds require the most delicate handling. Limit soaking to 5 to 10 minutes maximum, not the full 15 to 30 minutes. Avoid ultrasonic cleaners, steam, solvents, and harsh detergents entirely. These can dissolve oil or resin treatments applied to enhance clarity.
Even lab-grown emeralds may carry clarity treatments. The controlled growth environment reduces inclusions but does not eliminate the use of finishing treatments that improve the stone's appearance. When in doubt, the warm soapy water method with a soft brush and a short soak is the safest choice for any stone.
What to Avoid, and When to Take Your Jewelry Off
Remove your jewelry before:
- Swimming in chlorinated pools or hot tubs. Chlorine degrades metal alloys and accelerates plating wear.
- Applying skincare and fragrance. Lotions, perfumes, hairspray, SPF, retinol, and AHA serums all contain chemical actives that dull surfaces and stress plating over time.
- Exercising or cleaning with household chemical products.
The interaction between modern skincare routines and fine jewelry is underappreciated. Acids and exfoliants in daily skincare can gradually wear metal surfaces. The simplest rule: put jewelry on last, after skincare and fragrance have fully absorbed.
A note for rhodium-plated S925 pieces: avoid silver dip, silver polishing cloths, and toothpaste. All three will damage the plating.
Ultrasonic cleaners are safe for diamonds and durable lab-grown sapphires and rubies in secure settings. Never use them on emeralds or on plated jewelry, where vibration can accelerate plating wear.
Storage: The Final Step in the Care Ritual
Store each piece separately. Diamonds scratch softer metals and stones; tangled chains stress settings and clasps. Separation is the simplest form of protection.
For S925 pieces, use airtight pouches or bags with anti-tarnish strips. Limiting exposure to sulfur compounds and moisture significantly slows tarnish formation, even on unplated sterling. Keep all pieces away from direct sunlight, humidity, and temperature extremes. A consistent, dry environment is ideal.
DHARIN pieces arrive in packaging designed for ongoing storage. The pouch is part of the care system, not just presentation. Use it.
If a rhodium-plated piece begins to show wear over time, professional re-plating is available. Contact DHARIN directly to discuss care and service options for your piece.
Wear It With Intention, and Confidence
Care is not about fragility. It is about extending the life of something made to be worn, daily and deliberately.
A piece cared for correctly becomes more personal over time, not less valuable. It carries the marks of a life lived, held together by considered craftsmanship and a few minutes of attention.
DHṚ: to hold, to sustain, to carry. Care is the practice of permanence.
