Of course, the two are completely different - cubic zirconia (CZ), is a lab-created synthetic material, while zircon is a naturally occurring gemstone with a very different chemical composition.However, before the introduction of diamond simulants like cubic zirconia and moissanite, white zircon was actually one of the most popular diamond substitutes, owing to its high dispersion and refractive index, and was often marketed under the misleading trade name of 'Matura diamond'.

Blue zircon is one of the traditional modern birthstones for December.

Zircon is a tremendously important mineral, indeed its prominence led to the emergence of the discipline of 'zirconology' in gemology.

Zircon in its purest form is completely colorless (white), but owing to trace impurities, it can occur in a wide range of interesting colors, including yellow, orange, red, green, blue, violet, brown and combinations in between.

Yellow-brown to orange and red zircon are the most common occurrences, along with colorless.

Zircon is also remarkably dense and exhibits a very pronounced level of birefringence.
