How to care for a fine engagement ring

A well-made engagement ring does not demand much. The metal is resilient, the stone harder than anything it is likely to encounter in ordinary life, and the craftsmanship, if it was done correctly, does not degrade from ordinary wear. But “does not demand much” is not the same as “needs nothing at all,” and a small amount of care applied consistently produces a ring that still looks new in twenty years.

Cleaning

The most common source of visual decline in engagement rings is not wear or damage — it is the accumulation of residue between the stone and setting. Soap film, hand cream, cooking oils, and natural skin oils collect underneath and around the stone, filling the spaces behind the facets and reducing the light return of even an excellent diamond to a fraction of its original brightness.

Cleaning this is straightforward. A small bowl of warm water, a few drops of mild dish soap, and a soft toothbrush. Soak the ring for five minutes, then gently brush around the setting and under the stone. Rinse under running water and dry with a lint-free cloth. This alone will restore most of the brilliance that accumulates residue.

Do this approximately once a week if the ring is worn daily. It takes three minutes and produces a noticeable improvement. If you wear hand cream or work with your hands in any capacity, more frequent cleaning is warranted.

Chemicals to avoid

Bleach and chlorine damage gold alloys over time. Immersing a ring in chlorinated pool water repeatedly will, over months and years, affect the metal’s structural integrity at solder points. Take the ring off before swimming in a chlorinated pool.

Hand sanitisers — which became standard daily use during the pandemic and have largely remained so — contain alcohol at concentrations that do not harm gold or platinum but can, over time, affect certain gemstone treatments and adhesives used in pavé work. For a solitaire diamond in a standard prong or bezel setting, hand sanitiser is essentially harmless. For a pavé-set ring with many small stones, I would suggest removing it or applying sanitiser before putting the ring on.

Strong abrasive cleaners, including many commercial jewellery cleaning solutions, are harsher than the warm water and soap approach and unnecessary for routine maintenance.

Prong inspection

Once or twice a year, look at the prongs holding the central stone under good light — or better, under mild magnification if you have access to it. Each prong should be a complete, rounded tip. If any prong looks worn, thinned, or has developed a sharp edge, have it inspected by a goldsmith immediately. Worn prongs are the primary cause of stone loss, and they are easy and inexpensive to address if caught early.

Do not attempt to push a prong back into place yourself. The forces required to move gold are larger than they appear, and uncontrolled pressure on a setting will cause more damage than the original wear.

Professional maintenance

A professional clean and inspection once a year — or at minimum every two years — is worthwhile for any ring worn daily. A goldsmith will check prong integrity, re-tip any prongs that are showing wear, polish out surface marks, and clean areas that home cleaning cannot reach. For rings I have made, I offer this service at cost for the life of the ring.
