11 Carat Emerald Cut VVS1 Hebridean Grey Moissanite Space Diamond | 12 × 14 mm

11 carats. Hebridean Grey™. VVS1 clarity. A monumental emerald-cut moissanite with unmistakable presence.

Experience the extraordinary depth and brilliance of this ~11 ct Hebridean Grey Moissanite Space Diamond, precision cut into an elegant 12 × 14 mm Emerald Cut.

Its distinctive Hebridean Grey body colour combines smoky silver, gunmetal, and charcoal tones with the extraordinary fire of moissanite, while the long step facets of the emerald cut create broad flashes of light, mirrored reflections, and exceptional visual depth.

Inspired by the shifting Atlantic skies, stone, sea, and storm light of the Hebrides, Hebridean Grey gives this gem a character completely different from conventional colourless moissanite.

At approximately 11 carats, this is not a subtle gem.

It is designed for collectors, statement jewellery, bespoke engagement rings, pendants, and one-of-a-kind commissions where scale, geometry, and individuality matter.

HEBRIDEAN GREY. EXTRAORDINARY PRESENCE.

Hebridean Grey is Gemdrop®'s distinctive interpretation of Fancy Grey moissanite.

Rather than trying to imitate a colourless diamond, this gem embraces its rich grey body colour, producing a sophisticated, contemporary appearance that changes dramatically with the lighting and viewing angle.

Expect tones ranging from:

• Smoky grey

• Gunmetal

• Silver-grey

• Charcoal

• Storm-cloud grey

• Bright spectral fire under direct light

In softer light, the gem can appear cool, restrained, and architectural. Under stronger illumination, the same crystal comes alive with intense flashes of colour and brilliance.

Hebridean Grey — inspired by Atlantic skies, stone, and storm light.

THE EMERALD CUT

Clean lines. Broad flashes. Architectural brilliance.

The emerald cut is defined by its elongated rectangular outline, clipped corners, and carefully arranged step facets.

Unlike brilliant cuts, which produce countless smaller flashes of light, an emerald-cut moissanite creates larger, more deliberate reflections across the gem.

At 12 × 14 mm, those broad step facets create a dramatic hall-of-mirrors effect while showcasing the depth and distinctive grey colour of the crystal.

The substantial proportions make this gem particularly suited to:

• Statement rings

• Alternative engagement rings

• Men's jewellery

• Pendants

• Collector pieces

• Bespoke jewellery commissions

~11 CARATS OF MOISSANITE

This is an exceptionally large loose moissanite gemstone.

At approximately 11 ct and 12 × 14 mm, it delivers the visual impact expected from a serious statement gem while retaining the durability and extraordinary optical performance for which moissanite is renowned.

For jewellery designers and collectors searching for a large grey gemstone, grey moissanite, Fancy Grey moissanite, emerald cut moissanite, or an alternative diamond gemstone, Hebridean Grey™ offers something genuinely distinctive.

VVS1 CLARITY

The exceptional clarity of the crystal allows the geometric step-cut faceting to remain crisp and visually clean.

VVS1 clarity indicates an exceptionally clean visual character, with inclusions extremely difficult to detect under magnification and not readily visible to the unaided eye.

This is particularly important in an emerald cut, where the broad open facets reveal more of the interior of the crystal than many brilliant-cut designs.

The result is a remarkably clean gem with impressive transparency, depth, and optical precision.

MORE FIRE. EXCEPTIONAL BRILLIANCE.

Moissanite is crystalline silicon carbide (SiC) and one of the most optically powerful jewellery gems available.

With a refractive index of approximately 2.65–2.69 and dispersion of approximately 0.104, moissanite produces intense brilliance and spectacular spectral fire.

Its dispersion is substantially higher than diamond, creating vivid flashes of rainbow colour when the gem interacts with direct light.

With a Mohs hardness of approximately 9.25–9.5, moissanite is also exceptionally resistant to scratching and suitable for jewellery intended for regular wear.

THE ORIGINAL SPACE DIAMOND

Moissanite has one of the most unusual stories in gemmology.

In 1893, Nobel Prize-winning scientist Henri Moissan discovered tiny crystals of silicon carbide while examining material associated with Meteor Crater in Arizona.

The mineral would later be named moissanite in his honour.

Natural moissanite is extraordinarily rare. Gem-quality moissanite used in jewellery today is laboratory-grown as high-purity silicon carbide crystal.

Gemdrop® celebrates this remarkable scientific heritage through our Space Diamond collection.

Space Diamond is the Gemdrop® collection name for our moissanite gems.

A GEM THAT DOESN'T TRY TO BLEND IN

Colourless gems are designed around purity.

Hebridean Grey is about character.

The combination of an enormous ~11 ct size, atmospheric grey body colour, crisp 12 × 14 mm emerald cut, and VVS1 clarity creates a moissanite unlike conventional colourless jewellery gems.

It is bold without being loud, dark without losing brilliance, and sophisticated without sacrificing fire.

For a collector, designer, or jewellery maker looking for a truly distinctive centre stone, this is exceptional.
