Lapis lazuli has a very long history and is artificially processed at the remains of the Egyptian Nakada Cultural Age (Naqada / 3300-3100 BC) before the beginning of the dynasty, discovered at the burial sites of the Neolithic and Mehelgarh ruins (now as Pakistan). Often polished and processed into gems, sculptures, mosaic decorations, vases, etc. In addition, it has been widely used as a blue pigment since the times of Egypt, Sumer, Babylonia, etc., and many of the powdered one "Ultramarine" is used in tempera (an opaque paint made of eggs, glue, resin, etc.)The deep blue color peculiar to lapis lazuli is the negative ion of sulfur contained in the crystal. In addition, the slight amount of substances contained in the interior creates subtle changes in color. For example, if it contains calcite, white streaks will appear, and if it is pyrite, you will see golden color speckled. Since lapis lazuli is a highly durable stone, it is processed into various items such as watches and figurines in addition to jewelry. It is said that the stones that the most beautiful ones are those that have been cut into flats, and the highly regarded stones are used for flat cutting and carving, so it can be said that this point is significantly different from opal and turquoise. Flat-cut stones are often used for cufflinks and men's rings, and have a standardized thickness of 2.5 mm. Current sources includes Afghanistan, Russia, Chile, Myanmar and the United States. The highest quality is from Afghanistan and also high quality in Argentina.
