Why Fine Jewellery Needs Regular Maintenance

Diamonds and precious gemstones endure daily contact with cosmetics, skin oils, lotions, hand soaps, and dust. Because diamonds are naturally lipophilic (oil-attracting), a thin microscopic film accumulates on pavilion facets within days of regular wear, dulling their refractive performance.

Safe At-Home Cleaning Routine

For diamonds, sapphires, rubies, and solid gold or platinum jewellery, the safest and most effective cleaning routine requires simple household materials:

  • Step 1: Soak in a bowl of warm water mixed with a few drops of mild, phosphate-free dishwashing liquid for 15 minutes.
  • Step 2: Use a soft-bristled baby toothbrush to gently scrub behind the stone and around the basket where oils gather.
  • Step 3: Rinse thoroughly under warm running water (ensure the sink drain is securely plugged).
  • Step 4: Pat dry with a lint-free microfiber lens cloth.

Gems That Require Delicate Handling

Certain gemstones must never be submerged in hot water or placed in ultrasonic machines:

Emeralds are porous and often oil-treated; ultrasonic vibrations strip natural oils, making internal fractures starkly visible. Pearls, opals, and tanzanite have low hardness or moisture sensitivity and should only be wiped clean with a damp, soft cloth.

“Always put on jewellery LAST after perfume, hairspray, and lotion have completely dried on your skin.”
