Jasper is a part of quartz that is crystalline, dark red or dark brown, may be yellowish or green, and is rarely blue. Its common red color is due to iron impurities as well as very fine granules

The jade appears under the microscope in the form of fine granules as well as fibers or small balls of silica. In general, it can be said that the physical properties of jade are very similar to the physical properties of quartz.

The jade is used in ornamental works since it was used by humans since antiquity in the manufacture of wood engraved and serrated, and used in the manufacture of some cheap ornaments.
