Cubic zirconia is a synthetic gemstone that closely resembles the appearance of a diamond. It is made from a crystalline form of zirconium dioxide, which is created in a laboratory under controlled conditions. The gemstone’s name reflects its cubic crystal structure, which gives it exceptional brilliance and sparkle.

Cubic zirconia has gained popularity as an affordable alternative to diamonds due to its visual similarity and significantly lower price. It possesses a high refractive index, meaning it can reflect and refract light in a way that creates vibrant flashes of colour and a brilliant shine.
