Phanerite
Igneous rock composed of crystals visible to the naked eye / From Wikipedia, the free encyclopedia
A phanerite[1] is an igneous rock whose microstructure is made up of crystals large enough to be distinguished with the unaided human eye. In contrast, the crystals in an aphanitic rock are too fine-grained to be identifiable. Phaneritic texture forms when magma deep underground in the plutonic environment cools slowly, giving the crystals time to grow.

Phanerites are often described as coarse-grained or macroscopically crystalline.
