EXCEPTIONAL SIZE. UNRIVALLED PRESENCE.

At 13 mm (8 carats), this is an extraordinary statement gem. Its exceptional size allows the precision-engineered Round Brilliant cut to unleash remarkable brilliance, producing an abundance of intense white light and vivid spectral fire from every angle.

Designed for those who appreciate exceptional sparkle and commanding presence, this gemstone is ideal as the centrepiece of a bespoke engagement ring, luxury pendant, heirloom commission, or fine gem collection. It offers a level of visual impact reserved for truly exceptional stones, while leaving room above it for Gemdrop's flagship 12 carat moissanite.

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

With a hardness of 9.25–9.5 on the Mohs scale, it is exceptionally resistant to scratching and ideally suited to jewellery intended to be worn and enjoyed for generations.

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.
