How to clean and care for lab-grown diamond jewelry

The 5-minute home cleaning routine

Once a week (or whenever the stone looks dull): soak the piece in warm water with a drop of dish soap for 10–15 minutes. Then brush gently behind the stone with a soft toothbrush — the underside of a diamond collects the most film, because that is where lotion and soap residue settle. Rinse in warm water and pat dry with a lint-free cloth.

That is it. No special products required. The film that dulls a diamond is ordinary grease, and dish soap dissolves it.

• Do use: warm water, dish soap, soft toothbrush, lint-free cloth.
• Do not use: toothpaste (too abrasive), bleach (attacks metal alloys), vinegar or lemon juice on gold settings.
• Ultrasonic cleaners are fine for solid diamond solitaires, but skip them for treated stones or pieces with soft gem accents.

What actually damages diamond jewelry

Diamond scores 10 on the Mohs scale, so nothing in daily life scratches the stone itself. The vulnerabilities are around it:

• The metal. 14k and 18k gold are soft. Gym equipment, sand, gardening and household cleaners all scratch or erode the setting — and a worn prong is how stones get lost.
• Chlorine and pool chemicals corrode the alloys in gold over time, weakening prongs.
• Sudden knocks can chip a diamond along its grain, especially at the girdle edge — rare, but it happens with hard impacts.
• Lotion, sunscreen and hairspray build a film that blocks light and kills the sparkle. Put jewelry on last, take it off first.

Storage: why your ring hates the jewelry box

Diamonds scratch diamonds — and everything else. Tossing several pieces into one box lets stones scratch each other and drag across soft metals. Store each piece in its own soft pouch or a box with separate compartments, and keep the original case: it is designed for exactly this.

For travel, a padded roll or the original box beats a zip pocket. Hard impacts are the main risk in transit.

The yearly 20-minute check

Once a year, have any professionally-set piece checked: a jeweler will tighten prongs, re-polish the metal and ultrasonic-clean the stone. It is quick, usually free where you bought the piece, and it is the single best insurance against losing a stone.

Between checks, watch for warning signs yourself: a prong that looks flattened, a stone that spins in its setting, or a rattling sound when you tap the piece near your ear. Any of those means stop wearing it and send it in.

Everlum pieces ship with a lifetime warranty on craftsmanship — if a setting fails under normal wear, we repair or remake it. Message us with a photo and we will take it from there.

Do lab-grown diamonds need any special care?

No. A lab-grown diamond and a mined diamond are the same material — chemically and physically identical — so cleaners, ultrasonics and care routines apply equally to both.

The one lab-specific note: some lower-quality growth processes leave a grayish tint at the surface of poorly-cut stones. That is a buying-quality issue, not a care issue, and it is exactly what certification filters out. Every Everlum stone over 0.5 ct ships IGI-certified, so you know what you are getting before it arrives.
