How to Identify Granite?
Firstly, granite is a natural stone with several distinctive visual characteristics. These features make it easy to recognise granite:
Recognising the texture of granite:
To begin, this stone has a granular texture that is visible to the naked eye. It is composed of visible minerals such as quartz, feldspar, and mica, which appear as grains of varying sizes.
Additionally, you can recognise granite by its granular texture, which provides a unique appearance and a rough touch sensation.
Colour variations:
Moreover, granite comes in a wide range of colours. Common shades include grey, pink, white, black, yellow, and brown. The colour of granite often depends on the geographical area where it is extracted.
There are also fascinating colour variations and patterns in granite, created by the presence of different minerals and their uneven distribution within the rock.
These variations give granite a natural and unique beauty that fits well with many landscaping projects.

Shine and Stone Finishes:
Granite has a natural shine due to its composition. When polished, it can achieve a reflective, mirror-like surface.
This polishing process enhances its colour and fully reveals its texture and patterns.
Granite’s appearance can vary depending on the finish. A sanded finish provides a smoother texture and highlights the grains and crystals in the stone. A flamed finish improves grip, while a bush-hammered finish adds more texture and a rougher surface.
Hardness and Durability:
Granite stands out from other natural stones due to its hardness and resistance to wear.
On the Mohs scale, which measures mineral hardness, granite typically ranks between 6 and 7, making it much harder than stones like limestone or travertine.
As a result, granite is less likely to be scratched or damaged by daily wear. Its durability makes it a preferred material for high-traffic applications, such as flooring and outdoor landscaping projects.
Porosity Test:
Granite has low porosity, meaning it absorbs very little water. You can perform a porosity test by dropping a few drops of water onto the stone’s surface and observing whether the water is absorbed or remains on the surface.
Natural stones with higher porosity, such as marble and limestone, tend to absorb water more quickly.
