What Is Cubic Zirconia? CZ vs. Diamonds

Want diamond-level shine without the diamond-level price? Cubic Zirconia (CZ) is the go-to stone behind BLNG's most-worn pieces—bright, durable, and made for everyday flex.

What Is Cubic Zirconia (CZ)

CZ is a lab-created crystal engineered to deliver serious sparkle. Because it's grown in controlled conditions, you get ultra-clean clarity and consistent color—perfect for tennis chains, pendants, and iced Cubans.

CZ vs Diamonds — Side-by-Side

Look & Sparkle: Diamonds have a classic white brilliance; CZ brings bold fire (those rainbow flashes) for a louder shine on camera.
Hardness & Durability: Diamonds are a 10 on the Mohs scale; CZ is about 8–8.5—tough enough for daily wear with smart care.
Color & Clarity: Diamonds vary widely (and you pay for the "perfect" ones). CZ is typically near-colorless and clean out of the box.
Price: CZ lets you go bigger in width and stone count without blowing the budget.
Ethics: CZ is lab-grown—no mining, fully traceable.

Bottom line: Diamonds = heritage and rarity. CZ = maximum look for the money and zero stress.

Why BLNG Uses CZ

Big sparkle in slimmer profiles (think 3mm and 4mm tennis).

Everyday durability when paired with our heavy 18K plating over premium metals.

How to Pick Quality CZ Jewelry

Cut & Setting: Stones should sit straight with smooth prongs (no snags).
Finish: Even color on links and clasp; no patchiness.
Hardware: Box clasps should "click" and lock; bracelets shouldn't wobble.
Brand Standards: Look for heavy plating and clear materials info.

Width & Length Quick Picks (Tennis & Cubans)

3mm Tennis: minimalist daily shine; layers with anything.
4mm Tennis: more presence while staying classy.
12mm Cuban: statement energy—wear solo or over a tee.

Lengths that land: 50 cm (20") as a universal sweet spot, 55 cm (22") for a touch more drop, 60 cm (24") for relaxed fits.
