How to Clean Cubic Zirconia Jewelry So It Sparkles Like New

To clean cubic zirconia, soak the jewelry for 10 to 15 minutes in warm water with a few drops of mild dish soap, brush gently behind and around each stone with a soft toothbrush, rinse in clean warm water and pat dry with a lint-free cloth. That is all most CZ needs to look bright again.

Cubic zirconia rarely loses its sparkle because of the stone itself. It looks cloudy when oils, lotion and soap build up on its back facets and block light. Here is how to clean it properly, what to avoid and how to keep settings secure, especially on solid gold pieces with pave stones.

Why cubic zirconia looks cloudy

Cubic zirconia is a lab-made crystal, hard and very clear when clean. Its sparkle depends on light entering the top, bouncing off the angled facets underneath and coming back out. A thin film of skin oil or hand cream on those lower facets stops that light from returning, so the stone looks milky or flat.

The usual culprits are:

• Hand cream, body lotion and sunscreen
• Soap residue from washing hands while wearing rings
• Hairspray and perfume
• Natural skin oils and dust trapped under settings

The good news: this film comes off with gentle washing. If you want to know more about CZ itself, our cubic zirconia jewelry guide explains how it is made, and diamond vs cubic zirconia compares the two honestly.

How to clean cubic zirconia step by step

1. Prepare: fill a small bowl with warm water, not hot, and add a few drops of mild dish soap without moisturizers or added scents.
2. Soak: leave the piece for 10 to 15 minutes to loosen oils.
3. Brush: use a soft baby toothbrush to clean the top of each stone, then tilt the piece and brush underneath, where most buildup collects.
4. Rinse: rinse under warm running water, with the sink plugged or a strainer underneath.
5. Dry: pat dry with a lint-free cloth. A quick blast from a hairdryer on its cool setting clears water from settings.
6. Buff: finish with a soft, dry cloth to polish the metal.

A round halo pendant or a classic four-prong solitaire are the pieces that benefit most, because light passes through a large center stone and shows every bit of film.

Cleaning methods compared

Pave and small-stone pieces

Pave means many tiny stones set close together, each held by small beads or prongs of metal. These pieces collect oils quickly but also need the gentlest handling.

• Brush in one direction and keep pressure light so bristles do not lever stones.
• After cleaning, hold the piece near your ear and tap it gently. A faint rattle can mean a loose stone.
• Look over the piece in good light for gaps where a stone used to be.
• Avoid ultrasonic cleaners for pave unless a jeweler has checked the settings.

Heart studs with pave CZ and a bezel-set emerald-cut solitaire show the two extremes: the studs need careful brushing between tiny stones, while a bezel setting surrounds the stone with metal and is very secure.

What to avoid

• Hot water: sudden temperature change is hard on any stone and setting.
• Harsh chemicals: bleach, chlorine pools and strong household cleaners can dull gold over time.
• Abrasive powders and pastes: they scratch the gold around the stones.
• Silver dip solutions: made for silver, not gold and CZ together.
• Wearing CZ while applying products: put lotion and hairspray on first, jewelry last.

Cleaning CZ on the go

Traveling or between proper cleans, you can still keep CZ bright. A lens-cleaning wipe without alcohol, or a soft cloth slightly dampened with water, removes fingerprints from the top of a stone. It will not reach the back facets, which is where most of the haze builds up, so treat it as a quick refresh rather than a substitute for a soak. Avoid hand sanitizer wipes, which leave their own residue and are harsh on any pearls or enamel in the same piece. When you get home, give the piece a full wash and dry it properly before putting it away, because a damp setting stored in a closed box can trap moisture around the stones.

How often to clean CZ

For rings worn every day, a quick clean every week or two keeps them bright. Earrings and pendants need cleaning less often, roughly every month. A deeper soak every few months, followed by a check of the settings, is a good habit. Our jewelry maintenance checklist puts all of this into a simple routine.

Does cubic zirconia scratch or wear out?

CZ is hard, harder than most things it meets day to day, so it resists scratches well. Over many years of daily wear, especially on a ring, the edges of the facets can pick up tiny abrasions and the stone may look slightly less crisp. Gentle storage helps: keep CZ pieces apart from each other and from diamond jewelry. See how to store gold jewelry for ideas.

The solid 14K gold around the stones is softer than CZ and takes most of the wear. Unlike plated jewelry, it will not flake or reveal another metal underneath. Our lifetime guarantee covers craftsmanship, so if a stone ever comes loose, message Şerif directly. Browse CZ pieces in our earring collection.

Frequently asked questions

Why does my cubic zirconia look cloudy?

Usually because oils, lotion or soap residue have built up on the back of the stone and block light. A gentle soak and brush normally restores the sparkle.

Can I clean cubic zirconia with vinegar?

We do not recommend it for gold jewelry. Mild dish soap and warm water clean CZ effectively without exposing the metal to acid.

Is an ultrasonic cleaner safe for CZ?

For sturdy settings in solid gold it is generally fine, but vibration can loosen small pave stones, so hand cleaning is safer for those pieces.

Can I wear cubic zirconia in the shower?

Water alone will not harm CZ in solid gold, but soap and shampoo leave a film that dulls the stone. Read our guide on showering with 14K gold for details.

How do I know if a CZ stone is loose?

Tap the piece gently near your ear and listen for a rattle, and check for any movement when you touch the stone with a fingertip.
