Pentelikon marble is flawless white with a uniform, faint yellow tint, which makes it shine with a golden hue under sunlight. It is white, fine-grain marble that has been quarried at Mt. Pentelikon north of Athens since the 1st millennium BCE. Pentelic marble was used for sculpture as well as for buildings.
Pentelic marbles often contain inclusions or veins of iron oxide, graphite, mica, or pyrite. Graphite inclusions in marble, called graphitic marble, show as gray or silver flakes when polished.
