Black Galaxy (also known as Star Galaxy) is one of the most recognisable granites in the world. Its dramatic jet-black background studded with brilliant golden and silver star-like flecks — caused by bronzite mineral inclusions — has made it a global icon for luxury kitchens, hotel lobbies and premium architectural features. This guide covers everything a buyer needs to know before placing an order.
Where Does Black Galaxy Come From?
Authentic Black Galaxy granite is quarried exclusively from the Nandyal region of Andhra Pradesh, India — specifically around the Ongole and Kurnool districts. It is not found anywhere else in the world in comparable quality, which makes genuine Nandyal Black Galaxy a geographically specific product.
Be cautious of suppliers offering "Black Galaxy" from other Indian states or countries — these are imitation stones that do not match the mineral character, fleck density or polish quality of the original.
Understanding Black Galaxy Quality Grades
Black Galaxy is typically supplied in three quality grades. Understanding these grades is essential for specifying the right material for your project and ensuring you are paying a fair price.
| Grade | Fleck Density | Background Colour | Best For |
|---|---|---|---|
| Premium | High — dense gold flecks | Pure jet black | Luxury countertops, hotel lobbies, feature walls |
| Standard | Medium — even distribution | Deep black with slight variation | Flooring, cladding, general countertops |
| Commercial | Low — sparse flecks | Black with grey areas | Budget projects, paving, secondary applications |

Slab Sizes and Thickness
Black Galaxy is available in slabs up to 280×160cm, with standard thicknesses of 1.8cm, 2cm and 3cm. Jumbo slabs are occasionally available from select quarries. Cut-to-size is possible in any dimension within the slab limits.
Polish Quality: What to Specify
Black Galaxy reaches its full visual impact only at high gloss levels. Always specify a minimum of 100 GU (Gloss Units) on your purchase order and request a gloss-meter certificate with your shipment. Lower polish levels (below 90 GU) significantly reduce the visual impact of the gold flecks.
Pricing Factors
Black Galaxy pricing varies based on grade, slab size, thickness and quantity. Premium grade commands 30–50% above commercial grade pricing. Key price drivers include:
- Fleck density and uniformity (higher density = higher price)
- Background colour purity (jet black vs grey patches)
- Slab size (larger slabs are scarcer and more expensive)
- Volume ordered (container-load pricing significantly lower than LCL)
- Finish specified (polished standard; honed and leathered at premium)
