Where it comes from
Black Galaxy is quarried in a small belt around the town of Chimakurthi, in Andhra Pradesh's Prakasam district. The deposit is a gabbro — a coarse-grained igneous rock — with bronze-coloured biotite mica flecks distributed through a deep black ground.
It is the most-exported Indian granite by volume. We have shipped it to 28 of the 30 countries we work with — to Saudi homes, to Texan kitchens, to Italian palazzos. The reason is simple: the look is dramatic, the price is sensible, the durability is uncompromising.
How to grade a Black Galaxy slab
Three things matter: the fleck size, the fleck density, and the slab uniformity. Premium-grade Black Galaxy has medium-to-large bronze flecks at a consistent density across the slab — when you look at a 9-foot slab, the 'starfield' should be evenly distributed, no bald patches, no clumps.
Commercial-grade Black Galaxy has smaller, sparser flecks, often with visible 'rivers' of pure black. Both are honest products, but they look different installed. Always view the actual slab — never buy from a chip sample.
Where it works
Kitchen islands and countertops, full stop, is where 60% of our Black Galaxy ships. The contrast against white or cream cabinetry is one of the most successful design pairings in the industry.
It also works as flooring in formal commercial spaces (lobbies, boardrooms), as exterior cladding for premium commercial buildings, and as vanity tops in master bathrooms. We avoid recommending it for high-traffic public flooring in honed finish — the matte surface shows water spots more than polished.
Finishes and what they change
Polished: the standard finish. Mirror-bright, makes the bronze flecks pop, easiest to clean. Honed: matte finish, softer look, hides scratches better but shows water spots. Leather: a subtle textured finish, increasingly popular for modern minimalist interiors, hides fingerprints brilliantly.
For a kitchen, polished is the default. For a contemporary vanity, leather is the more interesting choice.
Watch out for
Black Galaxy has cheaper substitutes — Star Galaxy and various Chinese 'galaxy' granites. These are different stones with different flecks (often coated to enhance shimmer, which wears off). True Indian Black Galaxy carries a uniform mineral structure under inspection.
Sealing is recommended but optional — the stone has very low porosity. One seal at installation, then refresh every 5–7 years is plenty.
