General care

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.

Cleaning Gemstones

Gemstones are durable, 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 porous gemstones like lapis, turquoise, malachite, opal, or onyx. They should be gently wiped clean with a moist cloth. These gemstones will absorb chemicals, like soap, which can build up inside the stone and discolor it.

Organic gems like pearls, coral, and amber should only be wiped clean and dry with a moist cloth. Due to their organic nature, these gems are both soft and porous, so as a general rule avoid bathing with them. Be careful with hairspray, cosmetics, and perfume. The chemicals in those products can permanently damage organic gems (especially pearls) over time.


Cleaning 14K Gold Filled

14K Gold Filled is highly tarnish resistant, however, sweat, lotions, perfumes, and normal wear can dampen its beautiful gold shine. Fortunately, gold filled  jewelry is easy to clean! All you need is a jewelry cloth made for polishing gold, which has a chemical that removes dirt, grime, and tarnish. We have these available for sale here. If your order was $50 or more, we sent you one for FREE because we're cool like that.

Expert Tip: Don't confuse tarnish with the actual gold rubbing off. This won't happen to KOZAKH 14K Gold Filled, but it will happen to gold plated jewelry you buy elsewhere. 

Cleaning Sterling Silver

Sterling Silver is a precious metal that jewelers have loved to use for thousands of years, including us! Sterling Silver has one issue - it is prone to tarnishing (think grandmas antique silverware). Believe it or not, wearing your Sterling silver jewelry is a great way to keep tarnish from building up, but if you do end up leaving it off for a while and notice its not looking so hot, don't worry! All it takes is a quick dip in some silver cleaning solution, and it'll look brand new. Our favorite silver cleaner is eco-friendly Simple Shine.
