Informations supplémentaires

Lapis lazuli is a relatively rare semi-precious stone that has been prized since antiquity for its intense blue color. Lapis lazuli is a rock, largely formed from the mineral lazurite. Lapis takes an excellent polish and can be made into jewelry, carvings, boxes, mosaics, ornaments, and vases. It was also ground and processed to make the pigment ultramarine for tempera paint and, more rarely, oil paint. Its usage as a pigment in oil paint ended in the early 19th century when a chemically identical synthetic variety, often called French ultramarine, became available.
