The Asscher cut was first cut in 1902 by Joseph Asscher for the Asscher Diamond Company. This was the first patented diamond cut, since then there have been many patents for diamond cuts. The Asscher cut has 58 facets and it's patent expired during the second world war.

The Asscher Diamond Company has since restarted as The Royal Asscher Diamond Company and has redesigned the Asscher cut with 74 facets and patented it as the Royal Asscher Cut. This CZ stone is the original Asscher Cut with 58 facets.

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.
