A stunning, diamond-like shine that’s hard to tell apart from the real thing. Plus, with a hardness rating of 8.5 on the Mohs scale, they’re tough enough for everyday wear.

Whether you’re a jewelry designer sourcing top-tier stones, a student learning to set gems, or just someone who wants a beautiful, travel-friendly piece of jewelry, our CZ collection has something for you. We carry a wide range of shapes, sizes, and over 60 colors — from classic white to vibrant shades that mimic rubies, sapphires, emeralds, and more.

FAQs: Get to Know Cubic Zirconia

Q1: What is Cubic Zirconia, exactly?

Cubic zirconia (or CZ) is a lab-grown gemstone made from zirconium dioxide. It’s clear, hard, and sparkles beautifully — all without the mining. Because it’s man-made, it’s more affordable and doesn’t carry the same ethical concerns as mined stones.

Q2: How does CZ compare to a diamond?

To the untrained eye, high-quality CZ looks nearly identical to a diamond. It’s usually flawless and colorless, similar to a D-color, Flawless diamond. The main differences? Diamonds are harder (10 vs. 8.5 on the Mohs scale), and their sparkle is a little different — CZ tends to give off more rainbow-like flashes of light.

Q3: What does “AAAAA” mean?

5A (or AAAAA) is the top quality grade for CZ stones. These are cut and polished with great care to show off the best clarity and sparkle. They outshine lower-grade CZ stones like AAA in both brilliance and precision.

Q4: Is Cubic Zirconia strong enough for daily wear?

Yes! With a hardness of 8.5, CZ is more than durable enough for rings, earrings, pendants, and bracelets that you wear every day. It holds up well to regular use.

Q5: How should I clean CZ jewelry?

It’s easy — just like cleaning other fine jewelry. Use a soft brush, mild soap, and warm water. Rinse well and dry with a clean, soft cloth. Try to avoid strong chemicals or anything abrasive.

Q6: Do you offer colored CZ stones?

We do! In fact, we stock over 60 different colors. From pure white to deep blues, fiery reds, and unique custom hues, we have the perfect color for any design. contact us if you can't find the right color you need, we will make that for you.

Q7: Can CZ be used in jewelry that’s fired, like with metal clay?

Yes — our clear/white CZ stones are kiln-safe and can handle the high heat used in firing. They’re a favorite among artists working with metal clay or casting settings. Just a heads-up: some colored CZs may shift color under high heat, so we always suggest testing a single stone before doing a full piece.

Q8: What about 7A quality CZ — how does it compare to 5A?

7A is an informal term sometimes used by suppliers to describe cubic zirconia stones that are even more refined than standard 5A (AAAAA) quality. While there’s no universal grading system beyond 5A, “7A” usually refers to CZ stones that have been cut with extreme precision, have zero visible inclusions, and may mimic the optical properties of real diamonds even more closely.

Think of it as the ultra-premium tier — perfect for high-end jewelry pieces where that extra sparkle and detail matter. However, it’s worth noting that grading standards can vary by manufacturer, so always look at the actual stone quality, not just the label.
