Summer is the hardest season on diamond jewelry. Sunscreen, salt water, chlorine, and sweat all dull a stone's brilliance, and most owners only notice when a piece comes back from a trip looking grey instead of bright.

Lab-grown diamonds are just as hard as mined ones (10 on the Mohs scale), but the settings and surfaces around the stone are not. A summer routine takes about ninety seconds a day and adds years to how a piece looks. Here is the version that actually works.

The Last-On, First-Off Rule

The single most important habit: jewelry goes on last in the morning, and comes off first in the evening. That means after sunscreen, perfume, hairspray, and lotion, and before makeup removal or skincare. Every body product builds a film on diamond facets, and sunscreen is the worst offender because it bonds to oils and dries opaque.

The Three-Minute Daily Wipe

At the end of the day, remove each piece and run it under warm water with one drop of dish soap on a microfiber cloth. Gently wipe the back of the stone (this is where most film accumulates), pat dry, and store. That is it. No soaking required unless the piece looks visibly dull.

The Weekly Soak

Once a week, fill a small bowl with warm water and a few drops of mild dish soap. Soak rings, earrings, and pendants for 10 to 15 minutes, then brush gently with a soft toothbrush (a baby toothbrush is ideal), rinse, and pat dry with a lint-free cloth. Skip ultrasonic cleaners for pieces with prong-set stones; the vibrations can loosen settings over time.

What To Avoid In Summer

Salt water: remove jewelry before swimming in the ocean. Salt accelerates corrosion on gold settings, especially in alloyed gold below 18kt. Chlorine: worse than salt for gold, and can permanently dull the finish. Take rings off before the pool or hot tub. Sweat: not directly damaging, but it leaves a salty residue that builds up. A quick rinse after a sweaty workout keeps everything bright. Sunscreen: apply, let it absorb for two minutes, then put jewelry on.

Storage That Doesn't Wreck Your Pieces

Diamonds are the only thing that scratches diamonds. If pieces are tossed in a single tray, they will eventually mark each other and the softer gold around them. Store each piece in its own soft pouch or lined slot. For travel, a small folding jewelry roll with separate compartments is the move.
