Preciosa Cubic Zirconia (CZ) is a synthesised crystalline material made from zirconium dioxide, developed as a diamond simulant with a refractive index and visual brilliance closely approaching that of natural diamond. Unlike glass-cut crystal, CZ is rated 8 to 8.5 on the Mohs hardness scale, giving it exceptional durability for jewellery settings and everyday wear. Preciosa's proprietary cutting process uses diamond-cutting software developed in-house to maximise the optical properties unique to CZ, producing results that generic CZ stones cannot match.
