The Origin and History of Black Galaxy Granite

In 1983, Mr. K. Bala Krishna Reddy initiated efforts to promote the quarry’s material under “SHOBHA.” Despite several efforts, achieving success remained difficult to attain. There was a significant turning point when the lease was transferred to a different entity, leading to a strategic shift and a rebranding as “Galaxy Granite.” The decision led to the start of operations in 1987. The unique appeal of “Galaxy Granite” quickly found success, establishing a strong demand from both domestic and international markets. 

The globally renowned Galaxy Granite deposit is strategically situated in Chimakurthy, R.L.Puram, Budawada, and Devarapalem villages within the Chimakurthy Mandal of Prakasam District of Andra Pradesh State. The quarry zone is located along the Ongole – Nandyala State Highway road, covering a distance from the 23rd to the 26th kilometre stone.

Attributes and Characteristics of Galaxy Granite

The Galaxy Granite body is made up of a Norite/Gabbro rock, featuring unique golden-coloured Bronzite specks. This remarkable geological formation is a component of the Chimakurthy Anorthosite – Gabbro plutonic complex. This intricate formation, with its igneous characteristics, was inserted into the preexisting Sargurs and Easternghat mobile belt, which originated during the Archean era. The Galaxy Granite body in the Chimakurthy region is visually appealing and geologically significant due to its unique composition of Norite/Gabbro and the presence of golden Bronzite specks.

Black Galaxy Granite usually has a rich black background, although there may be some variations as below

  • Greenish/Black Shading or even
  • White in the background.

This stone is known for its vibrant broncite flecks, often called the “galaxy” feature. The distinct metallic specks found in Black Galaxy granite play a crucial role in determining its overall quality and desirability. These specks are classified based on their size.

Larger grains are highly sought after, though they are rare and come at a higher price. The granite comes in various grain sizes, including

  • Large-grained,
  • Medium-grained, and
  • Small-grained materials, each impacting the stone’s overall appearance.

Black Galaxy granite is a highly durable material that can withstand daily wear and tear with minimal maintenance required. Scratches can sometimes be a concern in areas with a lot of activity, especially if there is dust and debris present. This is especially noticeable on darker surfaces. It’s important to exercise caution when dealing with granite, particularly around edges and corners. Although it is a hard material, it can be brittle and susceptible to cracking or breaking if struck forcefully by a hard object. Taking proper care of this durable material will help it last for a long time.

Factors Determining the Quality of Star Galaxy

Several factors contribute to the quality, appeal, and price of Star Galaxy granite:

1. Lines (Veins): Black Galaxy granite of Grade A is completely line-free, whereas Grade B may contain a few black lines. Grade C can have more than two black lines, while Grade D may have multiple black and white lines. Lines have a noticeable effect on both the visual appeal and the cost.

2. Galaxy Size: The size of the colourful broncite flecks, known as “galaxy,” adds to the visual appeal of the granite. Bigger grains are in high demand due to their scarcity and typically have a higher cost associated with them.

3. Galaxy Distribution: The way the galaxy feature is spread out on the surface of the granite can impact how it looks overall. The stone’s appeal is boosted by a uniform even distribution.

By taking these factors into account, buyers can make well-informed decisions about the quality of Galaxy granite that aligns with their preferences and budget.
