Lapis

 Lapis:  is the Latin word for "stone" and Lazuli from the Arabic word "azula", meaning "blue".  Lapis is defined as a stone rather than a mineral because it is a mixture of several different mineral deposits. The most distinctive being the golden inclusions and/or veins of sparkling pyrite mixed within the deep blue color that makes Lapis so unique among gemstones. Lapis Lazuli is an opaque rock that mainly consists of diopside and Lazurite. It came into being millions of years ago during the metamorphosis of lime to marble. Lapis Lazuli is an opaque dark blue color, often with golden inclusions and whitish marble veins. Denim Lapis: is the trade name for the paler blue color phase of Lapis Lazuli, whose denim color has only become popular in recent years. Denim Lapis gets its color due to mixture with other minerals such as white calcite, occasionally speckled with yellow iron pyrites. Denim Lapis is generally not as expensive as Lapis Lazuli because it is considered a lower grade of the more popular dark blue Lapis color. It is found wherever Lapis is found: Afghanistan, Argentina, Russia, Chile, and the United States. Lapis Lazuli: is regarded by many people around the world as the stone of friendship and truth. The blue stone is said to encourage harmony in relationships and help its wearer to be authentic and give his or her opinion openly.
