Whilst not well-known, Zircon is in fact one of the world’s most important gemstones. It is frequently confused with the synthetic, lab-grown simulant for diamond – cubic zirconia – even though zircon is a naturally-found substitute for diamond. Adding to the disorder is the fact that zircon was misleadingly marketed as ‘Matura diamond’ for a time.

Colourless Zircon is revered for its evocatively named ‘fire’ – its flashes of multi-coloured light. Alongside with its brilliance, this property of Zircon is the basis of the comparisons to diamond, and makes it a firm favorite of collectors around the globe.



Zircon its most pure form, transparent and if colour is found it is due to small impurities – which can create violet, orange, red, green, yellow, blue and many other colours. Of these, Blue Zircon Stones are admired, yet its colour is attained by the heating of Brown Zircon.

Furthermore, some crystals contain harmless radioactive elements which break down the structure of the gem to form ‘Low Zircon’, which are prized by collectors for their rarity.
Whilst colourless Zircon is often cut ‘brilliant’ (as with diamonds), coloured gems can also be found in an Emerald step cut. If the stone is found round, it can be given its namesake ‘Zircon cut’, which boasts an extra row of facets around the edges of the standard round brilliant cut. These shapes aside, the most prevalent forms include rounds, pears, ovals and fancy trillions, and when polished, these stones show a fantastic, vitreous sheen.
