What is 5A zirconia?

5A Zirconia (also called 5A Cubic Zirconia or AAAAA-grade CZ) is the highest quality synthetic diamond simulant. This lab-created stone strongly resembles a real diamond in brilliance and clarity, but is much more affordable.

Cubic Zirconia is graded on a scale from A (lowest quality) to 5A (highest quality). 5A stands for:

• Perfect clarity: Completely colorless and without inclusions or cloudiness.
• Maximum brilliance: Precisely cut for optimal fire and sparkle.
• High hardness: 8.5 on the Mohs scale (diamond is 10), making it scratch-resistant and durable for daily wear.

At our company, sustainability is very important. Unlike the mining of real diamonds – a process that consumes enormous amounts of energy, leads to deforestation, soil erosion, and habitat destruction – 5A zirconia is created entirely in a laboratory. This makes it a conflict-free and more environmentally friendly choice, without the heavy ecological footprint of mining.

Our jewelry features exclusively 5A quality zirconia, for a luxurious appearance that is hardly distinguishable from real diamonds – but ethically responsible, sustainable, and at a fraction of the price.
