MODERN ELEGANCE. EXTRAORDINARY BRILLIANCE.

The 5 × 7 mm Radiant Cut is prized for combining crisp geometric lines with exceptional sparkle. Its trimmed corners and brilliant facet arrangement produce remarkable light return while maintaining the refined elegance of a rectangular gemstone.

• Engagement rings
• Fine jewellery
• Pendants
• Earrings

• Contemporary and classic jewellery designs

With exceptional VVS1 clarity and D colour, every facet contributes to outstanding brilliance, crisp light return, and vivid spectral fire under every lighting condition.

MORE BRILLIANCE. MORE FIRE.

Moissanite is one of the highest-performing gem materials available. With a refractive index of approximately 2.65–2.69 and a dispersion of 0.104, it produces substantially greater brilliance and spectral fire than diamond, creating extraordinary flashes of colour under both natural and artificial light.

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

With a hardness of 9.25–9.5 on the Mohs scale, moissanite is exceptionally resistant to scratching and ideally suited to jewellery designed to be worn and enjoyed 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 known, with gem-quality natural crystals being extraordinarily scarce.

Today, the world's finest moissanite is grown using advanced laboratory crystal growth techniques, producing gemstones of exceptional optical quality, consistency, and durability while preserving one of the most fascinating origin stories in gemology.
