For many people all over the world Lapis lazuli is considered a stone of truth and friendship. The blue stone is reputed to bring about harmony in relationships and to help ist wearer being an authentic individual who may openly state his or her opinion.
Lapis lazuli is an opaque stone consisting mainly of Diopside and Lasurite. It was created millions of years ago in the course of metamorphosis process turning chalk into marble stone. When unpolished, Lapis lazuli seems dull and dark blue, often with golden inclusions and whitish veins from marble. Contrary to former theories, however, the small twinkling and shining inclusions which lend the stone the attractive appeal of a star-spangled sky, are not gold but Pyrite, i.e., they are caused by iron. The blue colour, on the other hand, is caused by the sulfuric contents of Lasurite, and may result in purest ultramarine to pale blue shades. In comparison to other gemstones, the hardness is not too high and amounts to something between 5 and 6 on the Mohs’ scale
