Lapis

Lapis has been used in jewelry, carvings and amulets for thousands of years. It is a stone prized for its intense blue color. The name Lapis Lazuli comes from the Arabic word lazward, from which the word azure comes, which means blue. Ancient Romans used to call it “sapphires,” which was subsequently applied to the blue variety of corundum we know today as sapphire. Egyptians regarded lapis lazuli as a heavenly stone and often used it on the statues of their gods and in burial masks, as protection for the next life.
Lapis Lazuli is a blue rock made of several different minerals including lazurite, sodalite, hauyne, calcite (which shows as white flecks), and pyrite (which adds a golden yellow sparkle). The composition and color of each stone varies, but it’s the general intense dark blue color that is considered its best quality. Lapis lazuli has a uniform, massive appearance with distinct crystals, and can be semi opaque or opaque. Its color is of a strong, lively blue, sometimes with hint of violet. It often contains grayish or off-white patches or veins. The presence of these white patches reduces the value of the stone.
