The name lapis lazuli comes from ancient Persian. “Bleu” represents the color of the gem, et “or” represents the pyrite in it. Lapis Lazuli was used as a gem by the people of Iran, Egypt and India thousands of years ago, and was highly regarded by the emperors. It was also loved by the Eastern nations, especially the Arabs.
Lapis lazuli is named for its brilliant blue color with small pyrite particles. Lapis lazuli is a dense massive aggregate, and the fine grains have a cryptocrystalline structure. It is brittle, fragile when hit, and opaque. The colors are sky blue, light blue and blue-violet, with pure dark blue being the best.
The color of lapis lazuli is deep and stable, which can be used to make products that imitate bronze. In addition to being used as a gem material, lapis lazuli is also a paint color and dye.
Lapis lazuli is the best product with medium and pure color and is called “green gold”. The colors are dark blue, brilliant blue, bleu foncé, and navy blue, dense and thin, without impurities and white spots. En général, there is no gold star or few gold stars. This is the one with “green gold without gold”.
Poor quality lapis lazuli is often dyed to improve the color effect. When the dyeing depth is not large and there are obvious staining marks, it is easy to distinguish. Dyed lapis lazuli should be marked “disposal” when sold. En outre, it can be waxed to change the color and gloss. Le “Swiss green gold” often sold in the market is actually dyed chalcedony.
Afghanistan is the most famous producer of lapis lazuli.
