n. stone (Latin); lapis lazuli, deep blue mineral used as a gem; azure, sky-blue color

Lapis lazuli (sometimes abbreviated to lapis) is a semi-precious stone prized since antiquity for its intense blue colour.Lapis lazuli has been mined in the Badakhshan province of Afghanistan for 6,500 years, and trade in the stone is ancient enough for lapis jewelry to have been found at Predynastic Egyptian sites, and lapis beads at neolithic burials in Mehrgarh, the Caucasus, and even as far from Afghanistan as Mauritania.
