18K Solid Gold Care Guide

How to preserve the luster of your 18k gold jewelry

75% pure gold with 25% durable alloys – balances richness and resilience. Higher gold content means gentler care to avoid dulling.

Key Care Tips by Scenario

• Daily Wear: Remove before cleaning, swimming (chlorine damages shine), or using hairspray/makeup.

• Sports: Skip wearing during workouts – sweat and friction can wear down the metal and loosen gem settings.

• Travel: Store in anti-tarnish pouches (included with LUMIDIAM pieces) in a hard-sided jewelry case to prevent impact damage; avoid leaving in hot cars.

How to clean 18k gold jewelry

Mix mild, abrasive-free dish soap with lukewarm water. Soak for 10-15 minutes, scrub crevices with a soft brush, rinse thoroughly, and pat dry immediately (no air-drying – mineral deposits form!).

How to store 18k gold jewelry

Use divided, padded jewelry boxes in a cool, dry place. Add silica gel packets for long-term storage; keep separate from 14k gold/platinum to avoid scratches.

Gemstone Setting Care

• For diamond/sapphire settings: Avoid harsh chemicals (bleach, ammonia) – they can damage metal prongs.

• For soft gems (ruby, emerald): Use a microfiber cloth to wipe instead of brushing; ultrasonic cleaners may crack fragile stones.

• Have settings inspected annually by a jeweler to check prong tightness and gem security.

Why does my 18k gold look dull?

Buildup of oils/products or exposure to chlorine/saltwater. Regular gentle cleaning restores shine; professional polishing fixes minor scratches.
