If you are planning to buy Black Galaxy granite, this guide will help you understand everything – from origin, specifications, quality, pricing, applications, and how to choose the right supplier in India.
What Is Black Galaxy Granite and Where Does It Come From?
Black Galaxy Granite is a natural stone formed millions of years ago during the Precambrian period. Geologists call it a gabbric anorthosite, which means it formed deep underground from slow-cooling magma. The main color is rich jet black, and the sparkling flecks come from bronzite crystals that contain iron. These specks give the stone its famous galaxy-like look.
All genuine Black Galaxy Granite comes from a small area in Andhra Pradesh, South India. The main quarries sit near Chimakurthi village in the Prakasam district, close to Ongole town. Around 40 quarries spread across about 400 acres of land here. Each quarry covers between 2 and 20 acres and works on sheet bedrock, which helps produce large, consistent blocks. No other place in the world produces the exact same stone with this specific black base and golden sparkle. That is why buyers who want the real thing always look for a Black Galaxy Granite supplier India.
The stone forms in large solid sheets underground. Workers remove the top soil and then cut blocks carefully using modern wire saws and water cooling systems. This method keeps the blocks clean and reduces dust. Because the quarries sit in one concentrated zone, suppliers can maintain steady quality and supply throughout the year.

Technical Specifications and Physical Properties of Black Galaxy Granite
When you buy granite, you need to know its strength and how it behaves over time. Black Galaxy Granite performs well on every important test.
Density sits between 2.90 and 3.05 grams per cubic centimeter. This makes the stone heavier than many other granites, which adds to its solid feel and long life. Water absorption stays very low, usually between 0.04 percent and 0.20 percent. Low absorption means liquids do not soak in easily, so the stone resists stains better than softer materials.
Compressive strength ranges from 1,800 to 2,400 kilograms per square centimeter or higher, depending on the exact block. This high number shows the stone can handle heavy weight without cracking. Flexural strength, which measures bending resistance, falls between 12 and 18 megapascals. These numbers make it safe for floors, countertops, and even outdoor steps.
Hardness on the Mohs scale reaches around 6 to 6.5, which is typical for good granite. The stone takes a high polish that lasts for years. Porosity stays between 0.2 and 0.4 percent, so you do not need to seal it as often as some other stones, though sealing once a year still helps in busy kitchens.
The stone expands very little when heated, which reduces the chance of cracks near stoves or in sunny outdoor areas. Impact resistance is strong enough that a small object dropped from 68 centimeters usually causes no damage. All these properties come straight from the natural minerals in the rock, not from any added chemicals.
Unique Features That Make Black Galaxy Granite Special
- Deep velvet-like black background that gives a rich and luxurious look when polished.
- Natural golden and bronze-colored specks scattered across the surface, creating a stunning galaxy-like sparkle that catches light beautifully.

- Suppliers carefully sort the stone into different grades based on speck distribution and the presence of lines.
- Grade A (Premium): Perfectly even speck distribution with no visible black or white lines – the highest quality material.
- Grade B: May have one or two thin lines but still offers excellent appearance and value.
- Lower grades contain more visible lines and are often chosen for flooring or wall cladding where pattern consistency is less critical.
- Darker background with brighter, more vibrant gold flecks usually commands a higher price.
- The color and sparkle come from real mineral crystals (mainly bronzite) locked inside the stone – never painted or dyed.
- Unlike artificial stones, the beauty of Black Galaxy Granite never fades, even after 10 to 20 years of regular use.
- Every slab has its own unique natural pattern, making it feel exclusive and one-of-a-kind.

How to Choose the Best Quality Black Galaxy Granite?
Look at the slab in good light before you buy. The black background should be deep and even. Golden specks should spread nicely without large empty black patches. Avoid slabs with many white or black lines unless you want a lower grade for budget reasons.
Check the thickness and make sure it matches your project needs. Ask the supplier for test reports on water absorption and strength if you plan a big commercial job. A good Black Galaxy Granite supplier India will show you multiple blocks side by side so you can pick the exact pattern you like.
