6A cut cubic Zirconia is our highest grade of CZ, these are cut and graded to meet our 6A quality standard. This is cut with the highest quality material available on the market at the time of purchase and then cut by expert gem cutters to reach the standard of 6A.

Our White Round Brilliant Cuts are cut to meet this 6A standard and also cut to meet the hearts and arrows standard. This means that they will show a hearts and arrows pattern when viewed under a hearts and arrows viewer. The material used is the best available and the polishing is also the best available, making the most perfect round brilliant cut stone possible.

White Colour Description

We try to match the colour of the photos as close as possible with the colour of the gemstone, but like natural stones cz varies slightly in colour within the material and depth of colour varies with the size of the stone. Colour descriptions vary online and screen colour settings vary, so it is impossible to be spot on with the colour.

The colour white means that the stone is clear, matching a colour D diamond. Colour D is the clearest most colourless possible colour of a diamond.

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.

Small amounts of gems that can be easily told apart will be packaged together. If you would like to have them packed seperately there are options in the basket
