Know Your Materials: Moissanite, CZ, and S925 Silver

Before choosing a cleaning method, understand what your jewelry is made of. Moissanite is a lab-created gemstone with hardness rating of 9.25 on the Mohs scale—second only to diamond. Cubic zirconia (CZ) rates 8-8.5, making it durable but more prone to surface scratches over time. S925 sterling silver is 92.5% pure silver, making it soft enough to shape into intricate designs but prone to tarnish when exposed to air and moisture.

Because each material reacts differently to chemicals and physical stress, a single cleaning approach does not work for every piece. Browse moissanite pieces to see how these stones are set in different styles of jewelry, and notice how prong settings, bezel settings, and pave work affect which areas need attention.

Daily Habits That Protect Your Jewelry

The most effective care happens between wears, not just when you clean. Apply perfume, sunscreen, and lotions before putting on jewelry, and let products fully absorb first. Remove rings and bracelets before cooking, exercising, or doing dishes—oil, sweat, and abrasive cleaners all degrade metal finishes and dull stone brilliance over time.

Rinse your jewelry briefly under lukewarm water after wearing it, especially if you've been sweating or exposed to salty air. A quick rinse removes residue before it settles into hard-to-reach places like behind prongs or inside hollow ring bands. Dry immediately with a soft, lint-free cloth rather than letting pieces air-dry, which can leave water spots on silver.

Cleaning Moissanite: Safe Methods That Preserve Brilliance

Moissanite resists scratching well, but oils and grime accumulate on the stone's surface and reduce fire and brilliance. Clean moissanite every 1-2 weeks with this method: mix a few drops of mild dish soap with warm water, soak the piece for 5-10 minutes, then gently scrub with a soft-bristled baby toothbrush. Focus on the underside of the stone where oil from your skin collects most.

Rinse thoroughly under running water and pat dry. Avoid ultrasonic cleaners unless your moissanite is set in solid gold or platinum—ultrasonic vibrations can loosen stones from S925 silver settings over time. If your moissanite sits in a pave or micro-pave setting, skip vigorous scrubbing and instead let the piece soak longer to loosen debris without risking stone loss.

Caring for Cubic Zirconia and Colored Stones

Cubic zirconia is less scratch-resistant than moissanite, so never use abrasive cloths, baking soda paste, or toothpaste. These materials create microscopic scratches that cloud the stone's clarity. Instead, use the same mild soap and warm water method, but limit scrubbing to once weekly maximum.

For multicolor CZ pieces—like the colored cubic zirconia collection—be aware that heat and harsh chemicals can fade coatings on certain stones. Avoid steam cleaners and boiling water. If your colored CZ piece has gold plating, skip acidic cleaners like lemon juice and avoid ammonia-based jewelry dips entirely.

Polishing and Maintaining S925 Sterling Silver

Sterling silver tarnishes when exposed to sulfur compounds in air, sweat, and everyday products. Prevent tarnish by wiping pieces with a jewelry polishing cloth after each wear. For deeper cleaning, use a silver-specific cleaner or make a paste from baking soda and water only for unplated silver—never use this on gold-plated S925 pieces.

If you wear sterling silver rings daily, inspect the clasp and ring shank monthly for signs of thinning or damage. S925 is softer than stainless steel, so it bends and scratches more easily. Remove silver jewelry before swimming in chlorinated pools, and store it in an airtight bag when not in use to slow oxidation.

Storage Practices That Extend Jewelry Life

Store each piece separately to prevent scratching. Soft pouches, individual compartments in jewelry boxes, or plastic zip-lock bags all work well. For silver pieces, use anti-tarnish bags or add a piece of chalk to your storage area to absorb moisture. Keep pieces flat rather than stacking rings or earrings on top of each other.

For travel, use a hard-shell case with padded compartments. Avoid tossing loose jewelry into purses or pockets, where chains can tangle and stones can crack if impacted against keys or coins.

When to Take Jewelry to a Professional Jeweler

Bring pieces to a professional if you notice loose stones, bent prongs, or cracks in the metal. Have moissanite rings inspected annually if worn daily, especially those set in pavé or halo designs where small stones are more vulnerable to loss. Sterling silver chains with stretched or broken links need professional repair rather than home straightening, which can cause further damage.

Professional jewelers also offer deep cleaning with steam and ultrasonic equipment that removes buildup in places home cleaning cannot reach—behind stones, inside filigree, and beneath multi-row settings.

FAQ

Can I use toothpaste to clean moissanite jewelry?

No. Toothpaste contains abrasive particles that can scratch both the moissanite stone and the metal setting. Use warm water with mild dish soap and a soft toothbrush instead.

How often should I clean my S925 sterling silver jewelry?

Wipe silver pieces with a polishing cloth after every wear. Deep clean with silver-specific products once a month or whenever tarnish becomes visible. Frequent wear means more exposure to sweat and oils, so daily-use pieces may need cleaning every 1-2 weeks.

Can I wear moissanite and CZ jewelry in the shower?

It is not recommended. Soap residue, shampoo chemicals, and hard water deposits can accumulate on stones and dull their brilliance. Remove all jewelry before showering, swimming, or applying products in wet environments.

Does cubic zirconia lose its sparkle over time?

CZ is less durable than moissanite and may show surface scratches after years of wear, which reduces clarity. Avoid abrasive cleaners, store pieces carefully, and clean with gentle methods to extend the stone's lifespan.

Should I store sterling silver and moissanite together?

Yes, if both pieces are clean and dry. Keep different jewelry separated in individual pouches or compartments to prevent scratching between pieces, but mixing materials in storage does not cause chemical reactions.
