Egyptian Lapis was one of ancient Egypt's most sacred colors. Lapis lazuli traveled from Afghanistan to Egypt, valued like gold. Egyptians considered it the "stone of heaven"—they believed the sky was blue because of a massive lapis dome. Pharaoh masks, amulets, and tomb murals extensively used lapis blue. Tutankhamun's mask has lapis inlaid around the eyes. Egyptians ground lapis into eyeshadow—"Mesdematet"—possibly the world's first cosmetics. Cleopatra's blue eyeshadow was reportedly lapis powder.
