No. They are large and visible to the unaided eye.
Visible crystals or grains would be referred to as a coarse grained texture.

When all grains in a rock are large and easy to see, the rock is described as coarse-grained.
rocks with grains that can be identified with naked eye
Limestone can be both coarse-grained and fine-grained, depending on its composition and how it formed. Coarse-grained limestone typically contains larger mineral grains visible to the naked eye, while fine-grained limestone has smaller mineral grains that are not easily seen without magnification.

Granite is a coarse-grained igneous rock, meaning it is made up of large interlocking crystals. These crystals form as the magma cools slowly beneath the Earth's surface, allowing for the growth of larger grains rather than small ones.
A fine-grained igneous rock would likely weather faster than a coarse-grained igneous rock. This is because the smaller grains in a fine-grained rock provide more surface area for weathering processes to act upon, leading to quicker breakdown and erosion.
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
