The Stone

See the natural beauty of Galaxy Black up close — the surface texture, colour depth, and veining that make this granite unique.

Style:

Sparkle Exotic Polished

Earth's only source — exclusively quarried in Chimakurthy, India, this jet-black gabbro with shimmering bronzite crystals creates the iconic 'starry night' effect.

Galaxy Black granite is one of the natural world's most remarkable phenomena — a jet-black stone whose surface appears to contain an entire constellation of stars. Tiny golden-copper and silver bronzite mineral flecks shimmer against the deep black canvas like distant galaxies, creating the famous 'starry night' effect that has made this stone one of the world's most recognised and desired granites. What makes Galaxy Black truly extraordinary is its exclusivity. The stone is quarried exclusively near Chimakurthy (Ongole) in the Prakasam district of Andhra Pradesh — India's sole global source of this remarkable material. Geologically belonging to the gabbro family, its extraordinarily dense structure and fine crystalline composition mean that no other quarry on Earth produces a stone with exactly this combination of jet-black base and shimmering bronzite stars. In2stone considers Galaxy Black one of the true icons of natural stone. Its universal appeal crosses every design style — it works in minimalist contemporary kitchens, sleek modern apartments, traditional period properties, and luxury entertainment spaces. The sparkle never fades, never needs refreshing, and never fails to catch the eye. Our craftsmen handle Galaxy Black with the reverence this singular stone deserves, ensuring every installation reflects its extraordinary geological heritage.

Frequently Asked

Questions About Galaxy Black

What does Galaxy Black granite look like?
Galaxy Black granite features a deep, jet-black surface with scattered tiny golden-copper and silver bronzite mineral flecks that shimmer like stars in a night sky. The fine-grained, uniform texture provides a clean, minimal backdrop that makes the sparkling crystals appear even more dramatic. The overall effect is instantly recognisable — one of the world's most iconic natural stone patterns.
Why is Galaxy Black granite only from one location?
Galaxy Black is exclusively quarried near Chimakurthy in Andhra Pradesh, India — the sole global source. This geological uniqueness is due to the specific conditions under which the gabbro formed: the precise mineral composition that creates the bronzite crystal 'stars' against the jet-black base occurred only in this particular formation. No other quarry produces a stone with exactly this combination.
What kitchen styles suit Galaxy Black granite?
Galaxy Black's versatility is part of its appeal — it complements virtually any kitchen style. It's stunning in contemporary white kitchens for bold contrast, elegant in traditional designs with cream cabinetry, and sophisticated in dark, moody kitchens with charcoal units. The sparkle adds life to any colour scheme. It's particularly effective as a kitchen island against a lighter main worktop.
Does the sparkle in Galaxy Black granite fade over time?
No — the bronzite crystal sparkle is a permanent geological feature of the stone's mineral structure. It cannot fade, wear away, or diminish over time. Unlike applied finishes or coatings, the shimmering effect is integral to the stone itself. Your Galaxy Black worktops will sparkle as brilliantly in 30 years as they do the day they're installed.
How do you care for Galaxy Black granite worktops?
Galaxy Black granite is exceptionally low-maintenance. Clean daily with warm water and mild pH-neutral soap. Seal annually for optimal stain protection. The dark colour naturally hides many everyday marks, though water spots and fingerprints may be visible on the polished surface — a quick wipe with a dry cloth resolves this instantly. The dense gabbro structure provides excellent natural stain resistance.
★★★★★
"We decided to get bespoke granite work tops for our new kitchen and have to say that we are over the moon with them. From the outset, Ian was very professional when selecting the stone, he listened to what we wanted, went through all of the possibilities that we could have for our worktops and went through the process in detail once we had made a decision. The templateing and fitting was carried out by an incredibly professional and helpful team run by Kev, who knew exactly what they were doing and just got on and made my kitchen look amazing. I would highly recommend In2stone for a helpful, knowledgeable and professional service from start to finish."
