Yes, granite is known for having large mineral grains. This is one of the defining characteristics of granite, which is classified as an igneous rock with a phaneritic texture.

* Phaneritic means that the individual mineral grains are large enough to be seen with the naked eye.

This is in contrast to rocks like basalt, which have a fine-grained texture where the mineral grains are too small to be seen without a magnifying glass.

The large grains in granite are a result of its slow cooling process deep within the Earth's crust. The slow cooling allows the mineral crystals to have ample time to grow larger.
