Lapis lazuli is a rock composed of a mixture of several different minerals including lazurite, huaynite, sodalite, noselite, calcite and pyrite. Diopside, augite, mica, and hornblende may also be present in small amounts.

Up until the nineteenth century, lapis lazuli was ground up and mixed with oil to produce the deep blue-green pigment known as ultramarine which meant literally beyond the sea, as the lapis lazuli was brought from far away by ship. Since 1828, this pigment has been produced synthetically from a roasted mixture of kaolin clay, sodium sulfate and charcoal.
Lapis lazuli today is still a very popular lapidary material. It is made into a variety of hand-crafted objects such as carvings, spheres, beads and cabochon gems, as well as a great variety of lapis lazuli jewelry items.
