The Complete Cubic Zirconia Care & Durability FAQ
Proper cubic zirconia care keeps your wholesale inventory looking showroom-fresh for years. Many retailers quietly lose sales because CZ pieces lose their sparkle, pick up fine scratches, or develop a cloudy film from everyday wear. In this complete FAQ, Hengdian (HD) Jewelry explains what cubic zirconia really is, how hard it is, whether it is waterproof, and — most importantly — how to make cubic zirconia shine like new. Backed by our Shanwei (Haifeng) factory’s 18 years of production experience (since 2006), these are the care answers your B2B buyers actually ask for.

Section A — Sparkle & Shine: 5 Tips to Keep CZ Brilliant
Cubic zirconia throws more colourful fire than many buyers expect, but only when it is clean. A simple routine is the easiest way to make cubic zirconia shine between wears:
- Wash gently. Warm water with one drop of mild dish soap lifts skin oil and residue.
- Brush the settings. A soft-bristle brush reaches behind the stone where cloths cannot.
- Dry with microfiber. Always use a lint-free cloth — never paper towels, which can mark the plating.
- Store apart. Keep pieces in separate soft pouches so stones do not abrade each other.
- Avoid chemicals. Take jewelry off before perfume, hairspray, or chlorine exposure.
Section B — Hardness & Durability (Mohs Scale & Scratch Resistance)
On the Mohs scale, cubic zirconia hardness sits at about 8 to 8.5 — much harder than the metals it is set in and harder than quartz, yet a little softer than sapphire (9) and diamond (10). That places CZ durability firmly in “excellent for daily fashion jewelry” territory: it will not cloud from normal wear, though it is not indestructible. Treating it with the same care you would give a fine stone keeps it brilliant for seasons.
Section C — Waterproof & Hypoallergenic FAQ
Is cubic zirconia waterproof? The CZ stone itself is inert and not damaged by water. The catch is the 18K gold plating on the brass base: prolonged submersion and harsh chemicals can gradually dull the finish. We recommend removing pieces before swimming, showering, or cleaning, then drying them fully.
For sensitive skin, our 18K gold plated brass keeps nickel content within REACH-controlled limits, and the plating acts as a stable barrier for the vast majority of wearers.
Section D — How to Make CZ Look Like Diamond
With proper care, a well-cut stone can read convincingly like diamond. CZ actually has higher dispersion (about 0.060) than diamond (0.044), so it throws more colourful sparkle — the trick is keeping it clean and the setting crisp. Regular gentle cleaning, secure prongs, and a soft storage pouch are what make CZ look like diamond on the shelf and on the customer.
Frequently Asked Questions
How hard is cubic zirconia on the Mohs scale?
Cubic zirconia measures about 8 to 8.5 on the Mohs scale — harder than most jewelry metals and quartz, but softer than sapphire (9) and diamond (10). It is plenty hard for everyday fashion jewelry.
Does cubic zirconia scratch?
Yes, it can scratch, because it is softer than sapphire, ruby, and diamond. Store CZ pieces separately in soft pouches and avoid contact with harder stones to keep the surface polished.
Is cubic zirconia waterproof?
The stone is not damaged by water, but the 18K gold plating on the brass base can dull with prolonged submersion and harsh chemicals. Remove pieces before swimming or cleaning and dry them well.
How do I make cubic zirconia shine again?
Wash with warm water and a drop of mild soap, brush gently behind the stone, then dry with a lint-free microfiber cloth. Done regularly, this is the simplest way to restore the sparkle.
Is cubic zirconia hypoallergenic?
Our 18K gold plated brass keeps nickel content within REACH-controlled limits, and the plating forms a stable barrier for most wearers. We focus on compliant, consistent plating rather than absolute hypoallergenic guarantees.
