Sparkle Polished Fine Grain

The world's most famous star granite — India's legendary Black Galaxy features tiny golden bronzite flecks sparkling like a galaxy of stars against a jet-black night sky.

Black Galaxy is arguably the most iconic granite in the world. Quarried exclusively in the Chimakurthy region of Andhra Pradesh, India, this legendary stone features a jet-black base scattered with tiny golden-bronze bronzite mineral flecks that sparkle like distant stars in a clear night sky. The 'galaxy' effect is mesmerising — a surface that twinkles and shimmers as light and viewing angles change, creating a genuinely three-dimensional visual experience on a flat surface. The bronzite minerals that create Black Galaxy's signature sparkle are semi-precious stones in their own right. Their golden-bronze colour and metallic lustre are entirely natural, requiring no enhancement or treatment. This geological authenticity is what has made Black Galaxy one of the most enduringly popular granites globally — it has been specified by architects and designers for decades and shows no sign of losing its appeal. From high-end residential kitchens to luxury hotel lobbies, Black Galaxy's quiet drama works everywhere. Despite its celebrity status, Black Galaxy remains remarkably accessible. It sits at a competitive price point thanks to the scale of quarrying operations in Andhra Pradesh, making it possible for homeowners to bring this legendary stone into their kitchen without paying exotic-tier prices. It is genuine natural luxury at a sensible cost — the people's exotic.

Frequently Asked

Questions About Black Galaxy

What causes the golden sparkle in Black Galaxy granite?
The sparkling golden-bronze flecks in Black Galaxy are bronzite — a semi-precious mineral with a natural metallic lustre. These bronzite crystals formed within the stone millions of years ago and are embedded throughout the jet-black base. Each tiny crystal catches and reflects light at different angles, creating the signature 'galaxy' sparkle effect. The bronze colour is entirely natural and permanent.
Is Black Galaxy granite actually a true granite?
Geologically, Black Galaxy is classified as a gabbro — a type of intrusive igneous rock composed primarily of labradorite feldspar and pyroxene minerals. However, in the commercial stone industry, it is universally marketed and sold as granite, and its performance characteristics (hardness, durability, heat resistance) are comparable to true granite. The distinction is geological rather than practical.
Where exactly is Black Galaxy quarried?
Black Galaxy is quarried exclusively in the Chimakurthy area of Ongole, Prakasam District, Andhra Pradesh, India. This specific location, approximately 350 km from the state capital Hyderabad, has unique geological conditions that produce the stone's distinctive bronzite-studded black character. No other quarry in the world produces a stone with the same combination of deep black base and golden bronzite sparkle.
Does Black Galaxy granite show fingerprints?
On a polished surface, Black Galaxy can show fingerprints more readily than lighter-coloured granites, as the marks contrast against the dark, reflective surface. This is a common characteristic of all polished dark stones. If fingerprint visibility concerns you, a leathered or honed finish significantly reduces this issue while maintaining the stone's sparkle effect, particularly the leathered finish which adds texture.
Is Black Galaxy granite expensive?
Despite being one of the world's most famous granites, Black Galaxy sits at a mid-range price point — making it one of the best-value exotic stones available. The large-scale quarrying operations in Andhra Pradesh and the stone's enduring popularity help keep pricing competitive. You get genuine natural luxury with a globally recognised name at a price that is accessible to most kitchen renovation budgets.
★★★★★
"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."
