CARE GUIDE

How to care for your diamond jewellery.

A complete guide to keeping diamond rings, earrings, necklaces and bangles as brilliant as the day you bought them.

i.DAILY CARE

Keep Your Diamonds Brilliant for Years to Come

A little care goes a long way. With the right habits, your diamond jewellery will retain its sparkle and beauty for generations.

Put it on last, take it off first

Apply perfume, makeup, hairspray, and skincare before wearing your jewellery. This helps prevent residue from building up on diamonds and gold.

Wipe between wears

Use a soft microfibre cloth to gently remove oils, dust, and everyday buildup before storing your piece.

Check the setting once a month

Once a month, inspect rings and earrings for loose stones or prongs. If anything feels unusual, bring it to us for a professional inspection.

REMEMBER

Diamonds are incredibly durable, but the precious metal holding them requires care and attention.

ii.HOW TO CLEAN

How to clean diamond jewellery at home.

The safest and most effective way to clean diamond jewellery is with warm water and mild dish soap.

THE GENTLE SOAK METHOD

  1. Warm bowl.Soak your jewellery in warm soapy water for 10–15 minutes.
  2. Brush gently.Gently brush around the setting using a soft toothbrush.
  3. Rinse carefully.Rinse thoroughly with clean water.
  4. Pat dry.Pat dry with a lint-free microfibre cloth.

iii.STORAGE

Store it as you bought it.

Every diamond piece should live somewhere it can't touch another piece of jewellery. Diamonds will scratch gold, gemstones, and even other diamonds if they rub. That heaped tray on the dresser is doing damage you can't see yet.

  • Store Pieces Separately — Diamonds can scratch other jewellery, including other diamonds. Keep each piece in its own pouch or compartment.
    separate compartments work just as well.
  • Keep Chains Clasped — Store necklaces fastened and laid flat to prevent tangling.
  • Choose a Cool, Dry Place — Avoid storing jewellery in humid environments such as bathrooms.
  • Travel Smart — Use individual pouches or your original COSMOS jewellery box when travelling.
iv.WHAT TO AVOID

The short list of things that wreck jewellery.

Most damaged pieces we see in store didn't come from one big accident; they came from small, repeated exposure to things that quietly dull, scratch or warp.

To keep your jewellery looking its best, avoid:

DO Always
  • Store pieces separately

  • Remove jewellery before showering

  • Clean gently with a soft brush

  • Schedule regular inspections
DON'T
  • Swimming pools and hot tubs
  • Salt water exposure
  • Gym workouts and heavy lifting
  • Gardening and household cleaning
  • Bleach, ammonia, and harsh chemicals
  • Toothpaste and abrasive cleaners
  • Sleeping with hoops or dangling earrings

Specifically, stay away from:

  • Chlorine — weakens gold alloys over time. Take your ring off before the pool or hot tub.
  • Salt water — abrasive on settings and dulls rhodium plating on white gold.
  • Bleach & ammonia — can corrode gold and tarnish the metal around your diamond.
  • Ultrasonic cleaners at home — the vibrations can loosen prongs on older pieces. Leave this to the workshop.
  • Toothpaste — common online advice, surprisingly bad. It's mildly abrasive and will scratch gold.
v.BY PIECE TYPE

Care by Jewellery Type

Diamond Rings

The most frequently worn piece deserves the most attention. Remove rings before workouts, household chores, and any hands-on activity.

Diamond Earrings

Clean the backs regularly, where product buildup often collects.

Necklaces & Pendants

Perfume and body oils can dull chains over time. Wipe chains regularly and always store them clasped.

Bangles & Bracelets

Avoid impact against hard surfaces and store in protective pouches while travelling.
