FAQs: Get to Know Cubic Zirconia
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.
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.
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.
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.
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.

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.
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.
