Black Galaxy Granite in India: Origin, Properties, Price Factors and Uses
Black Galaxy Granite in India is a near-black natural stone with scattered gold and silver flecks, quarried mainly in the Chimakurthy area of Prakasam district, Andhra Pradesh. Geologically it is a gabbro, but the stone trade sells it as granite because it is similarly hard, takes a high polish and is processed with the same equipment. It has been part of Indian stone exports since the late 1970s.
The stone is recognised by name in international markets and is also sold as Star Galaxy Granite and Galaxy Gold Granite. Each slab is cut from a natural block, so the density and spread of the flecks differ from one slab to the next, a variation many buyers prefer over uniform, engineered surfaces.
This guide explains the origin, properties, price factors, finishes, common uses and care of Black Galaxy Granite in India, so architects, builders and homeowners can judge whether it suits their project.
What Is Black Galaxy Granite and Where Does It Come From?
Almost all Black Galaxy Granite in India comes from one place: the Chimakurthy belt in Prakasam district, Andhra Pradesh. That is geology, not marketing. The stone is not dyed or artificially darkened; the black base and the gold flecking are both natural, formed over hundreds of millions of years. It is why you will see the same stone sold as Star Galaxy Granite, Galaxy Gold Granite or Nero Galaxy Granite: same belt, same stone, different label.
What separates a good block from a mediocre one is how evenly the flecks sit across the surface, how deep and consistent the black runs, and how few natural fissures show on the face. Because every slab is cut from a quarried block rather than made to a fixed pattern, no two look quite the same. That is normal for natural stone, not a defect.
Geology of Black Galaxy Granite: Why It Is Technically a Gabbro
Black Galaxy Granite in India is not a true granite. It is a gabbro, made mostly of plagioclase feldspar mixed with biotite and other dark minerals, which produce the metallic gold and white specks against the black. The trade still calls it granite because its hardness, polish and finishing process are similar.
| Property | Typical Value |
|---|---|
| Origin | Chimakurthy, Prakasam District, Andhra Pradesh |
| Base Colour | Deep black with gold/white mineral flecks |
| Density | Approx. 2.9–3.0 g/cm³ |
| Hardness | Approx. 4.5–5 on the Mohs scale |
| Water Absorption | Approx. 0.05%–0.1% (very low) |
| Common Finishes | Polished, honed, flamed, leathered, bush-hammered, brushed |
| Standard Forms | Slabs, tiles, countertops, cladding panels, flooring |
The water absorption figure matters more than most people realise. A stone this dense barely lets moisture in, which is why it holds up in bathrooms and outdoor installations where a more porous stone would stain or crack under monsoon conditions.
Black Galaxy Granite Price in India: What Affects the Cost?
Black Galaxy Granite price in India is quoted per square foot or per slab, and rates vary across the market depending on how the stone is sourced and processed. Rather than a single figure that goes stale when demand shifts, it is more useful to know what moves a quote up or down:
Thickness
16–18mm tiles cost less than 20mm or 30mm slabs used for countertops and heavy-duty flooring.
Finish
Polished is the baseline; leathered, flamed and bush-hammered finishes involve extra processing and cost more.
Slab Grade
Even flecking, deep consistent black, and minimal fissures push a block into a higher grade.
Order Volume
Bulk orders for large commercial or export projects typically get better per-square-foot rates than small retail lots.
Slab Size & Random vs. Calibrated
Random-size blocks are cheaper than calibrated, gauged slabs cut to precise dimensions.
Delivery Location
Freight from Rajasthan or Andhra Pradesh to site adds to the landed cost, especially for export orders.
Because rates shift with market conditions and project specifics, the most reliable number is a current, project-specific quote.
Best Uses of Black Galaxy Granite in India
Its density, hardness and low water absorption make the stone suitable for interior, exterior and commercial work. These are the applications where Black Galaxy Granite in India is used most often:
Kitchen Countertops
Polished, it shrugs off day-to-day knife marks and cookware scuffs, and the dark surface hides minor stains a lot better than pale stones do.
Flooring
In homes and busy commercial spaces alike, the hardness means it holds its finish under heavy foot traffic for years, not months.
Wall Cladding
Interior feature walls and building exteriors benefit from how the surface catches light, especially under angled lighting.
Outdoor Use
Low water absorption makes it a safe bet for stairs, garden edging, and pool surrounds, even through Indian monsoons.
Hospitality Projects
Hotels and office lobbies use it often; it reads as upscale without fighting for attention against everything else in the room.
Facades & Lobbies
Large-format polished panels are a common choice for entrance facades where a strong first impression matters.
Why Architects and Designers Choose Black Galaxy Granite
Designers reach for Black Galaxy Granite in India when a project needs something that reads as neutral but still feels expensive. It works with brass and gold fixtures just as well as with chrome and stainless, which gives it more flexibility across styles than many competing black stones. On commercial jobs, its durability also means fewer maintenance headaches down the line.
It also photographs well, which matters when a project will be marketed through real estate listings, hotel brochures or restaurant interiors. The gold flecking picks up light in a way that reads as rich rather than flashy, and a near-black surface with natural flecking hides seams, minor scratches and daily wear far better than a pale or single-tone stone, so the finish still looks sharp years after handover.
Black Galaxy Granite vs Absolute Black and Steel Grey Granite
Buyers often reach this page while comparing black stone options. Here is how Black Galaxy Granite in India compares with two other common choices:
Black Galaxy
- Deep black with gold/silver flecks
- Sourced from Andhra Pradesh
- Best for a bold, "starry" look
- Ideal for feature walls, countertops
Absolute Black
- Uniform, near-solid black
- No visible flecking
- Best for a minimal, sleek look
- Common in modern kitchens
Steel Grey Granite
- Grey base with darker veining
- Lighter overall tone
- Best for brighter, airy interiors
- Popular for flooring on a budget
Most buyers choose between these based on the look they want for the space, not because one is objectively better. All three perform well as durable, low-maintenance granites for Indian conditions.
How Tripura Stones Selects and Processes Black Galaxy Granite in India
Every Black Galaxy Granite block we bring in is checked for colour consistency, mineral distribution and structural soundness before it goes near a cutting blade. Our facilities in Rajasthan handle cutting, polishing and finishing with calibrated machinery, which matters most on large orders where dozens of slabs need to match each other rather than look like they came from different quarries.
Block Selection
Blocks are inspected on-site for flecking consistency, black-tone depth, and fissure count before purchase.
Cutting & Gauging
Blocks are cut into slabs or tiles to the required thickness using calibrated machinery at our Rajasthan units.
Polishing & Finishing
Slabs are finished in the requested surface: polished, honed, flamed, leathered, bush-hammered, or brushed.
Quality Check
Finished pieces are checked for consistency across the batch, especially important for large commercial orders.
Packing & Dispatch
Slabs and tiles are packed for safe transit to residential, commercial, and export destinations.
Black Galaxy Granite Finishes: Polished, Honed, Leathered and More
The same stone feels completely different depending on how it is finished:
Polished
Mirror-glossy, maximises the sparkle in the gold flecks. The most common choice for countertops and feature walls.
Honed
Matte, low-sheen, softens the contrast between the black and the flecks. Often the better pick for flooring, where grip matters more than shine.
Flamed / Bush-Hammered
Textured and non-slip, built for outdoor paving and stair treads.
Leathered
Slightly textured, hides fingerprints and light scratches better than a full polish. A popular choice for kitchen islands that see a lot of hands.
Brushed
A soft, worn texture that mutes the shine while keeping the flecking visible. Used where a less formal look is wanted.
How to Care for Black Galaxy Granite
It is a low-maintenance stone, and a few habits go a long way:
Seal it every year or two
Absorption is low, but not zero; sealing protects against oils, acids, and pigmented spills.
Skip the acidic cleaners
Vinegar and citrus-based products will dull the polish over time. A pH-neutral stone cleaner does the job without the risk.
Use trivets and cutting boards anyway
It handles heat and scratches better than most stones, but there is no reason to test that with your good pans.
Re-polish when it needs it
High-traffic floors will dull eventually; a professional re-polish every few years brings the shine right back.
If you are weighing Black Galaxy Granite in India against other stone options for a kitchen, floor, or facade, it helps to see actual slabs and finishes before deciding. Photos rarely capture how the flecking catches light in person. Tripura Stones works with architects, builders, and homeowners across residential and commercial projects, and can walk you through finish options, slab consistency, and what is realistic for your space.
Frequently Asked Questions About Black Galaxy Granite in India
Where does Black Galaxy Granite in India come from?
It is quarried almost entirely in the Chimakurthy belt of Prakasam district, Andhra Pradesh. The same stone is also sold as Star Galaxy Granite, Galaxy Gold Granite and Nero Galaxy Granite.
Is Black Galaxy Granite a real granite?
Technically it is a gabbro, not a true granite. It is sold and classified as granite because its hardness, polish and finishing behaviour are similar.
What is the price of Black Galaxy Granite per square foot in India?
Pricing depends on thickness, finish, slab grade, size and order volume, so rates vary between suppliers and change with market conditions. Contact our team for a current, project-specific quote.
Is Black Galaxy Granite good for kitchen countertops?
Yes. Polished, it resists everyday knife marks and cookware scuffs, and the dark surface hides minor stains. Sealing every year or two is still worth doing, especially where oils and spills are a daily occurrence, and trivets and cutting boards remain good practice.
Which finish is best for Black Galaxy Granite flooring and walls?
Honed or flamed finishes make more sense for flooring, where slip resistance matters. Polished finishes are the usual choice for walls and countertops, where shine is the point.
How can I tell if Black Galaxy Granite is genuine?
Genuine stone shows natural, irregular flecking that varies across the slab, a consistent deep-black base, and no dye bleed at cut edges. Buying from a supplier who controls the process from block selection through finishing, like Tripura Stones, reduces the risk of substitutes.
