Browse our natural Ceylon zircon collection, certified loose gemstones in rich green hues, sourced directly from Sri Lanka. Zircon is a genuine mineral with natural brilliance rivalling diamond, and it is completely different from cubic zirconia despite the similar name.
Natural zircon is the oldest mineral on Earth, with some crystals dated at 4.4 billion years old. Cubic zirconia, by contrast, is a lab-created synthetic material developed in the 1970s. Natural Ceylon zircon has a refractive index close to diamond, giving it exceptional fire and lustre. It was historically used as a diamond substitute long before cubic zirconia existed.
Our collection focuses on naturally green Ceylon zircon, a rarer colour variety than the more common blue and colourless forms. Both stones in this collection are untreated cushion cuts, 1.84ct and 2.63ct, priced from $600 AUD. Zircon scores 7-7.5 on the Mohs scale and is durable enough for pendants, earrings, and occasional-wear rings.
No. Zircon is a natural mineral formed in the Earth over billions of years. Cubic zirconia is a synthetic lab-grown material. They share a similar name but are chemically, optically, and historically unrelated.
Blue zircon is typically heat-treated. Our green zircon stones are natural-colour and untreated. Treatment status is disclosed on every certificate.
