This 2.63ct natural Ceylon green zircon exhibits a distinctive green hue with the exceptional brilliance and fire that make zircon one of the most optically impressive gemstones. The rectangle cushion cut showcases the stone's high refractive index across its 8.04 x 6.30 mm face, producing flashes of spectral colour that rival diamond.

Natural zircon is one of the oldest minerals on Earth. Some specimens date back over 4 billion years. Despite this remarkable heritage, zircon remains one of the most underappreciated gemstones, often confused with its synthetic namesake cubic zirconia. The two are entirely different materials.

Zircon is NOT Cubic Zirconia

This is the single most important distinction for zircon buyers: natural zircon is a genuine gemstone with no relation to cubic zirconia (CZ). Cubic zirconia is a synthetic, lab-created material (zirconium oxide) used as a diamond simulant. Natural zircon is a zirconium silicate mineral that forms in the Earth's crust over billions of years.

Natural zircon actually outperforms many precious stones optically. It has a refractive index of 1.93-1.98 (higher than sapphire at 1.76-1.77) and exceptional dispersion (fire), meaning it splits white light into spectral colours more effectively than most gems. This is why well-cut zircons display remarkable brilliance and sparkle.

Origin & Certification

This zircon originates from Ceylon (Sri Lanka), one of the world's premier sources of natural zircon. Sri Lanka's gem gravels have produced zircon for centuries, and Ceylon zircon is particularly valued for its range of natural colours including green, golden, and blue.

The Arctic Gem Certification Laboratory (AGCL) has certified this stone, confirming its natural zircon identity, green colour, and Sri Lankan origin. The accompanying certificate provides independent verification of all stated characteristics.

Why This Green Zircon

Green is one of the rarest natural colours for zircon. While blue zircon (often heat-treated) dominates the commercial market, natural green zircon retains its colour as formed in the Earth. No treatment required. This rarity makes green zircon a compelling choice for collectors who value natural colour and geological significance.

At $650 AUD for a 2.63ct certified natural green zircon from Ceylon, this stone offers rare collector-grade value. The rectangle cushion cut maximises both brilliance and colour display, and the 8.04 x 6.30 mm dimensions provide excellent finger coverage for a ring setting or a striking pendant centrepiece.

For gem enthusiasts who appreciate the story behind their stones, few gemstones rival zircon. This mineral species predates almost all other gems on Earth, and owning a Ceylon green zircon connects you to geological history spanning billions of years.
