How to Care for and Clean Your Lab-Grown Diamond Jewelry at Home

Lab-Grown Diamond, Same Care Requirements

A lab-grown diamond is chemically and physically identical to a mined diamond. Same hardness, same thermal conductivity, same optical properties. So the care requirements are the same too. If you have ever maintained a diamond ring before, nothing about lab-grown changes the routine. If this is your first diamond, here is what actually matters.

What Dulls a Diamond Ring

Diamond itself does not scratch easily. It is the hardest natural material on earth, and scratching the stone is genuinely difficult under normal wear conditions. What does happen is buildup. Lotion, soap film, skin oils, and household products accumulate on the pavilion facets underneath the stone, and that is where the light re-exits the diamond on its way to your eye. Coat those facets in a film of hand cream and the ring loses its brightness. The stone is fine; it just cannot perform through a layer of buildup.

Metal scratches more easily, particularly yellow and rose gold. White gold develops the same fine surface scratches but hides them better because of the rhodium plating applied on top. Platinum scratches similarly to gold but does not thin over time the way gold does; it displaces rather than loses material, which is why platinum rings develop a satin patina rather than wearing down.

Everyday Habits That Help

Take your ring off before applying lotion, sunscreen, or any skin product. These are the biggest contributors to buildup and they go straight to the underside of the stone when you put the ring back on.

Remove the ring before swimming. Chlorinated pool water will not damage a diamond, but it can gradually affect the finish on certain metal alloys, and cold water causes fingers to contract, which occasionally results in rings sliding off in pools or the ocean. Neither outcome is worth the risk.

Take the ring off before cleaning with any product that contains bleach, ammonia in high concentrations, or abrasive compounds. These can damage the finish on gold and the prong tips over time.

When you are not wearing it, store the ring in a fabric-lined box or a small pouch, away from other jewelry. Diamond can scratch softer gemstones and even other metals if they are stored loosely together.

Cleaning at Home

The most effective and safest home cleaning method is also the simplest. Fill a small bowl with warm water, add a small amount of regular dish soap (not heavy-duty degreaser, not anything with moisturizers), and let the ring soak for 20 to 30 minutes. Then use a soft brush, a baby toothbrush works well, to gently scrub the underside of the stone, between the prongs, and along the band. Rinse thoroughly under warm running water. Pat dry with a soft lint-free cloth.

Do this once a week or every two weeks and the ring will stay noticeably brighter between professional cleanings.

What to Avoid

Avoid ultrasonic cleaners unless you are certain the setting is in good condition. These machines vibrate at high frequency and dislodge debris very effectively, but they can also vibrate a slightly loose prong until it fails. If you have not had a prong inspection recently, do not put the ring in an ultrasonic cleaner.

Avoid steam cleaners for the same reason. Thermal stress on a setting with weakened prongs can cause a prong to give way. Steam cleaning is a professional tool, not a home tool.

Avoid toothpaste. It is mildly abrasive and will leave fine scratches on metal surfaces over time. It also does not rinse cleanly from behind a stone.

When to See a Jeweler

Every six months is a reasonable cadence for a professional inspection. A jeweler can look at the prongs under magnification, check that the stone is still fully secure, polish the metal, and professionally clean the ring in ways that go beyond what a home soak achieves. If you have a pave band with many small stones, regular prong inspection is more important, not less, because small stones can work loose without being immediately obvious.

Beyond inspection, watch for any movement of the center stone. If the diamond rocks even slightly when you press on it with a fingertip, the ring needs attention before you wear it further. A loose stone is a stone at risk of being lost.

EX3 Diamond Warranty and Resizing

Every EX3 ring comes with a six-month warranty and 180-day free resizing. If you have a fit issue or a concern about the setting in the first six months, that is covered. After the warranty period, maintaining the ring through regular inspections keeps it in the best possible condition for decades of wear.

If you have questions about care for a specific setting style or stone shape from our IGI-certified lab-grown diamond collection, our team can advise you on the right routine for your ring. And if you are still in the selection process, our engagement ring collection includes notes on care requirements that vary by setting type.
