Introduce
Lapis Lazuli, the name comes from the Latin word “Lapis”, which means “stone”, and Lazuli means Lāzhvard’, the place where lapis lazuli is produced.
Lapis Lazuli usually contains 3-5 kinds of minerals, the blue part includes lazurite, sodalite, hauynite, etc.; the white part is calcite; the golden part is pyrite. As a result, it is technically a type of rock known as gemstone.
The majority of lapis lazuli appears opaque or translucent, and the range of its colors includes teal, blue, indigo and blue-violet. The different proportion and combination of minerals in the polycrystalline determines its color, for example, the greater content of azure stone makes lapis lazuli bright royal blue.

History of Lapis Lazuli

The main materials are pure gold and lapis lazuli, inlaid with precious and semi-precious stones, such as turquoise, lapis lazuli, carnelian, onyx, colored glass, clay, etc. The eyes are made of obsidian and quartz.

Painting Pigments
Lapis lazuli has been widely used as a painting pigment and can be found around the world, from the Dunhuang Mogao Grottoes in the East, the Dunhuang West Thousand Buddha Caves, to the murals in the tombs of Egyptian pharaohs and queens in ancient Egypt, which are more than 4,000 years old. Lapis lazuli is named “ultramarine” for the hue after ground is “beyond all colors”, its unique color is associated with the gods, calmness or majesty in any culture.
Before the Industrial Revolution, it was not easy for artists to use this kind of blue because lapis lazuli was a rare and expensive gemstone at the time, therefore only the nobility and the church could afford it. That is why lapis lazuli was often used to depict the robes of Christ or the Virgin Mary to symbolize their holy status. Back then, ultramarine was also called “Madonna Blue”.
Not all artists could afford to use pigments made from gemstones, and a single mistake could lead an artist to bankruptcy. A representative example of this situation is Vermeer, who loved ultramarine but thus trapped himself in financial trouble, and he’s the painter who created “Girl with a Pearl Earring”.

Medication
In Egypt and Babylon, lapis lazuli was used as a medicine for depression and fever, as well as in ancient Greece.
In India and Tibet, lapis lazuli is the symbol of Shiva, the god of destruction and rebirth, and Medicine Buddha, the god of healing. The locals ground lapis lazuli into powder and put it into medicine, either taken internally or applied externally. China also has relevant record of grinding lapis lazuli and calcite into powder and put into medicine for pregnant women to induce the babies, earning it the name “birthing stone”. There’s also an article in the ancient Chinese medicine scriptures “Compilation of Mongolian Prescription”, writing about the treatment of scabies, food poisoning and detoxification by decocting lapis lazuli.
Later, due to the technology developement and the high cost of gemstone, the medicinal use of lapis lazuli gradually diminished.
Commercial value of Lapis Lazuli
Ornamental
Lapis lazuli with rich blue, even color, fine quality without cracks, and uniform pyrite distribution is the best, and the highest quality lapis lazuli often does not contain pyrite. The value of lapis lazuli decreases sharply if pyrite oxidizes and turns black, or calcite forms white spots on the surface. Gem-grade lapis lazuli is often fashioned into cabochons or thin gemstone slices. Lower-grade lapis lazuli is typically used for making round beads or carving materials.
Generally, it is rare to find pure and flawless lapis lazuli. It is recommended that you can choose with “no white, less gold” or “uniform golden sprinkles”, just like holding the Milky Way in your hand, which is exquisitely fabulous.
