To maintain the beauty of your jewelry, whether it’s gold filled or solid gold, always avoid salt water, chlorine (swimming pools, jacuzzis) and all heavy detergents and cleaning agents. These harsh chemicals can damage all types of jewelry, so please remember to remove your pieces before coming into contact with these substances.
Gemstones are durable substances, yet they do need some care to maintain their luster. Follow these general guidelines, and yours will look brand new for years to come.
You can clean transparent gemstones simply by soaking them in water with a touch of soap. Use a soft toothbrush to scrub the stone.
Never use an ultrasonic cleaner or ammonia for cleaning opaque gemstones like lapis, turquoise, malachite or onyx. They should be wiped clean gently with a moist cloth. These gemstones can be porous and may absorb chemicals, even soap, which may build up inside the stone and discolor it.
Organic gems like pearls, coral, and amber should only be wiped clean with a moist cloth. Due to their organic nature, these gems are both soft and porous. Be careful about chemicals in hairspray, cosmetics, or perfume: they can, over time, damage pearls in particular.
Conclusion: When in doubt always use a warm moist cloth.
