If you have bought an 18K gold necklace, you already know how exquisite and valuable it is. Contrary to costume jewelry, gold jewelry requires some maintenance in order to preserve its beauty and luster. An 18K gold necklace consists of 75% gold and 25% other metals such as copper, silver, and palladium. Gold is highly durable, but compared to 10K and 14K gold, 18K gold necklaces require more maintenance so that their owners can enjoy their beauty for a long time.
Therefore, whether you wear your favorite 18K gold necklace every day or only on special occasions, this guide will provide you with practical tips on how to take care of your jewelry.
Why 18K Gold Necklaces Lose Their Shine
Before diving into maintenance tips, it helps to understand why gold jewelry dulls over time. 18K gold necklaces can lose their luster due to:
-
Daily exposure to oils, sweat, and skin products – Lotions, perfumes, and natural body oils build up on the metal's surface.
-
Contact with chemicals – Chlorine, cleaning agents, and even some cosmetics can react with the alloy metals in 18K gold.
-
Improper storage – Tangled or exposed necklaces are more prone to scratches and tarnish-causing air exposure.
-
Everyday friction – Rubbing against clothing or other jewelry gradually dulls the finish.
The good news? Because 18K gold contains more pure gold than 10K or 14K, it's naturally more resistant to tarnishing, but it's also softer, so it scratches more easily. That's why gentle, consistent care matters more than harsh cleaning.
Daily Habits That Protect Your 18K Gold Necklace
-
Put it on last, take it off first: Apply makeup, perfume, and hairspray before Wearing your necklace to avoid chemical buildup.
-
Remove it before swimming or showering: Chlorine and hot water can weaken the metal alloy over time.
-
Avoid sleeping or exercising in it: Sweat and friction accelerate wear and increase the risk of scratches or a broken clasp.
-
Wipe it after every wear: A soft microfiber cloth removes oils and prevents buildup before it sets in.

Storage Tips to Prevent Tarnish and Scratches
How you store your 18K gold necklace between wears matters just as much as cleaning it.
-
Store it flat or hanging, never balled up in a drawer.
-
Use a soft pouch or lined jewelry box to prevent contact with harder metals or gemstones.
-
Keep it away from direct sunlight and humidity, which can affect the alloy metals over time.
-
Store chains separately to avoid tangling and surface-to-surface friction.
When to Get Professional Cleaning
Even with great at-home care, professional cleaning once or twice a year is worth it especially for necklaces with intricate links like Cuban curb or figaro-style designs. A professional jeweler can:
-
Use safe ultrasonic and steam cleaning for deep buildup
-
Check and tighten clasps or jump rings
-
Spot early signs of wear before they become bigger problems
-
Re-polish the surface to restore that just-bought shine
