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.

	Diamond	Cubic Zirconia (Closer Match)	Moissanite
Refractive Index	~2.42	~2.15 – 2.18	~2.65 – 2.69
Dispersion (Fire)	0.044	0.060	0.104

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.

Category Description:

Please Note : Despite every effort to photograph these stones accurately there are some colours that do not show or come out wrong in the photograph. Each stone has a snakeskin pattern of intense colours that change from neon green to neon orange. The only way to see how the stone really looks is to buy a sample. These Lab created opals match the chemical properties of natural opal, but the impregnated patterns are resin to attempt to simulate the fiery patterns found in natural opals. This makes them look different to natural opals which have more intricate patterns which cannot be replicated synthetically.
