Why Buy from DiamondCZ?
1. Cubic Zirconia is the best diamond simulant
Despite the hype around moissanite, Cubic Zirconia remains the most realistic diamond simulant to the naked eye.
Its refractive index and dispersion are closer to diamond in appearance, resulting in a more natural sparkle. Moissanite, while often marketed as a superior alternative, sparkles too intensely and shows rainbow flashes that give it away.

2. Quality You Can Trust
Cubic zirconia is often misrepresented. Sellers may label 1A as 3A, or send a few good 6A samples but deliver lower-quality stones in the final order. Others mix poor-quality stones in larger packs without disclosing it.
3. 20 Years of Sourcing Gemstones
DiamondCZ has partnered with expert gem cutters for over 20 years to deliver true 6A, 5A, and 3A stones. With low overheads you’re paying mostly for the gemstone.
