Care and Keeping

Diamonds are the hardest material there is, so the diamond itself asks almost nothing of you. What needs care is everything around it: the metal that holds it, the clasps and backs that fasten it, and the small settings that, when they quietly loosen, are how a stone is lost. Good care is mostly attention, not labour.

Cleaning Diamonds lose their brightness less from damage than from film. Skin oil, lotion, and product build up on the underside of a stone, where light should enter, and dull it. The fix is simple: a bowl of warm water, a drop of mild dish soap, a soft toothbrush worked gently behind and around the stones, then a rinse and a pat dry with a soft cloth. Done every week or two, it keeps a piece bright. Avoid harsh chemicals, and be cautious with ultrasonic cleaners, which can shake loose an already-weak setting, though they are generally safe for solid diamond pieces.

Checking the setting This is the habit that saves pieces. Every so often, look and feel: does a stone move or sit proud, does a prong feel sharp where it has worn, does a clasp still close with a firm click, does an earring back still grip. A lost diamond almost always comes from a setting that had worked loose first and went unnoticed. Catching it early is the difference between a tightening and a loss. If you wear a piece often, have a jeweller check the settings once a year.

The parts that wear The stone outlasts everything around it. Clasps, earring backs, prongs, and thin chains are the parts that wear, because they are fine, they move, and they take the friction of daily wear. Treat them as the things to watch and, in time, to repair. Re-tipping a worn prong, replacing a clasp, or rebuilding a thin shank is normal maintenance on a piece worn for years, not a sign that something was wrong.

Storing Diamonds scratch other stones and metals, including other diamonds, so store pieces separately rather than heaped together, in a pouch or a lined box with compartments. Lay chains flat or hang them so they do not knot, since a knot pulled tight can kink or damage fine links.

A note on white gold and platinum White gold is plated with rhodium to stay bright white, and that plating wears over years and can be reapplied; if a white gold piece begins to look faintly warm or grey, it is due for re-plating, not ruined. Platinum develops a soft patina with wear, which can be left for a lived-in look or polished back to bright. Neither is damage. Both are simply how the metal ages.

How to think about it Care for diamond jewelry is light but regular: clean it often and gently, check the settings now and then, watch the parts that move, and store it so it cannot scratch itself. Do that, and a piece stays bright and secure for a lifetime, which is, after all, the point of buying well.
