MAXIMUM BRILLIANCE. MAXIMUM IMPACT.

At 12 mm (6 carats), this is a true statement gemstone. Its larger size allows the precision-cut Round Brilliant facets to generate exceptional light return, producing intense brilliance, vivid spectral fire, and dynamic flashes of colour that are impossible to ignore.

Whether viewed in daylight, indoor lighting, or direct sunlight, this moissanite delivers extraordinary optical performance and remarkable visual presence.

MORE BRILLIANCE. MORE FIRE.

Moissanite is renowned for its exceptional optical performance. With a refractive index of approximately 2.65–2.69 and dispersion of 0.104, it produces significantly more brilliance and spectral fire than diamond, creating intense flashes of colour under natural and artificial light.

Where diamond is singly reractive, moissanite is doubly refractive, contributing to its relatively greater, and distinctive, vibrant sparkle, fire, and exceptional light performance.

Its exceptional hardness of 9.25–9.5 on the Mohs scale also makes moissanite one of the most durable gems available, making it ideal for jewellery designed to be worn every day.

THE ORIGINAL SPACE DIAMOND

Moissanite was first identified by Nobel Prize-winning chemist Henri Moissan in microscopic crystals recovered from Arizona's Meteor Crater. Naturally occurring moissanite is one of the rarest minerals on Earth, making natural specimens exceptionally uncommon.

Modern moissanite is produced using advanced laboratory growth techniques to create gemstones with outstanding optical quality, consistency, and durability.
