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:

Properties Chemical Composition: Silicon Carbide (SiC) Hardness: 9.5mohs Refractive Index: nÏ‰=2.654 nÎµ=2.967 Melting Point: 2730 Â°C About Moissanite Moissanite was first synthesized in a lab before the natural mineral was found 2 years later by Henri Moissan in a meteor crator. Later Charles and Covard patented the mineral to be used to create gemstones. This patent has run out in 2018 so now anybody can legally create moissanite gemstones. Moissanite is visually close to a diamond, but has more fire than a diamond. CZ is a closer match to a diamond visually, but Moissanite is harder than cz and can pass as diamond with older electronic diamond testers, this will only work with moissanites (and diamonds) bigger than 2mm as smaller than 2mm is too small for most diamond testers. Moissanite can also pass the text test: That is if you put a round brilliant cut diamond on a piece of text (black on white paper) you cannot see any black, cz fails this test. Moissanite can also scratch Sapphire and scratch cz as it is harder.
