texture
Pegmatite texture is a coarse-grained igneous rock texture characterized by exceptionally large crystals. These crystals can be several centimeters to several meters in size. The slow cooling of molten rock in pegmatite formations allows for the growth of such large crystals.
It's texture is porphyritic
Texture
The size of the mineral crystals in an igneous rock determines the rock's texture.
Phaneritic is the texture of igneous rocks. These types of rocks crystallized slowly.

No, the texture of a rock is determined by its mineral composition, grain size, and how the rock formed (igneous, sedimentary, or metamorphic). Pigments refer to the coloration of a rock, which can be caused by the presence of specific minerals or impurities. Texture and pigmentation are separate characteristics of rocks.

Intrusive igneous rock has a coarse, visible crystalline texture. Intrusive igneous rocks are formed from slow cooling of magma. The additional time spent in a liquid state allows for the creation of larger mineral crystals. An igneous rock with a coarse texture is said to be phaneritic.
Pegmatite texture is a coarse-grained igneous rock texture characterized by exceptionally large crystals. These crystals can be several centimeters to several meters in size. The slow cooling of molten rock in pegmatite formations allows for the growth of such large crystals.
The size of crystals in an igneous rock is called texture. Texture can range from fine-grained (small crystals) to coarse-grained (large crystals).
