Care Guide
To preserve its timeless beauty, solid gold is naturally resistant to the ocean’s elements, while pearls should be kept away from sunscreen to maintain their luster. Diamonds and gold may be safely cleaned in ultrasonic machines; however, delicate gemstones and pearls require a gentler touch to ensure their brilliance endures.
To clean gold jewelry, use warm water with detergent-free soap and a soft brush, then polish with a jewelry cloth. Store in a soft bag or the original box to prevent scratches.
