Moissanite, CZ and Diamonds: What's the Difference?
Three stones show up in TABAT jewelry conversations: diamond, moissanite and cubic zirconia (CZ). Here is a plain comparison so you know exactly what you're buying — and what we don't sell.
At a glance
| Diamond | Moissanite | Premium CZ | |
|---|---|---|---|
| What it is | Crystallized carbon, mined or lab-grown | Silicon carbide, lab-grown | Zirconium dioxide, lab-grown |
| Hardness (Mohs) | 10 | 9.25 | 8–8.5 |
| Sparkle | Bright white flashes | More colored fire than diamond | White, slightly softer light |
| Wears over years | Indefinitely | Indefinitely with normal care | Very well; can dull after many years of hard wear |
| Where TABAT uses it | We don't sell diamonds | Solitaires, studs, pendants, eternity bands | Tennis bracelets, tennis necklaces, multi-stone pieces |
Why we split it this way
When a single stone carries the piece — a 2-carat solitaire, a pair of 7mm studs — it needs to be hard, lively and flawless up close. That's moissanite.
When the piece is a line of thirty small stones, what matters is that every stone is the same size, the same white, and set evenly. Premium 5A CZ does that beautifully, wears well, and keeps a tennis bracelet at a price you'll actually wear it at. Putting moissanite in a tennis bracelet would triple the price for a difference nobody can see on the wrist.
Will people be able to tell?
What gives away inexpensive jewelry is almost never the stone. It's the proportions, the thin metal, the yellowed plating, and the stones that don't match. We build to fine-jewelry proportions in real sterling silver with a rhodium finish, and we match every stone — so from normal distance, the piece reads as what it looks like: a well-made piece of jewelry. Up close, moissanite's extra fire is the only tell, and most people find it beautiful.
What about resale?
A diamond holds some resale value; moissanite and CZ don't. We think that's the wrong question for jewelry you wear every day. TABAT pieces are priced to be worn, not held as an investment — and they let you keep your fine jewelry for the moments it was bought for.
