Among the quality of cinnabar, the quality of cinnabar crystal is the best. This is because cinnabar crystal belongs to a single crystal and has a good metallic luster. After polishing, the overall permeability is very good, and the hardness is relatively low. In cinnabar, the quality of rootless sand and bloodstone is also very good. Among them, rootless sand is mainly translucent, and there will be few impurities. The cinnabar content of bloodstone is higher, and the quality will be better.
The cinnabar crystals in the cinnabar are of good quality. The main feature is that individual crystals also show a thick plate shape or rhombohedron. This kind of cinnabar metal has good gloss. After polishing, it will have better permeability, and the hardness is also the lowest, so it is easy to break. This is among the cinnabar, the most worthy of collection, and the highest value.
The quality of rootless sand in cinnabar is also very good. The rootless sand directly falls off from the cinnabar vein during the crustal movement, because it grows in the sediment and is formed after being eroded by the sediment. It is cinnabar with honeycomb and other holes. The shape it presents is very natural and beautiful, and it is also translucent, with very few impurities.
The better quality cinnabar can also be bloodstone. Bloodstone belongs to the ground stone in the cinnabar strip, because cinnabar directly penetrates into kaolin, or the ground stone. After a long time, it is formed. Moreover, the cinnabar content in bloodstone is very high, and it is very valuable for collection.
In addition to cinnabar crystals, rootless sand, and bloodstone, there are also powdered cinnabar, reduced cinnabar ore, and natural cinnabar ore. Among these, powdered cinnabar is the most common raw material for making cinnabar jewelry.
