The white spots left on obsidian usually indicate that there are some variations and uncertainties in the physical and chemical composition of obsidian. Sometimes these variations can bring people better quality and aesthetic feeling, but they may cause quality problems in some industries. Therefore, the white color on obsidian is an important reference factor for consumers to make purchase evaluation.

Obsidian's natural dark black texture is similar to the hair color commonly used in jewelry, so it has an irreplaceable position in jewelry. However, in the case of identifying and mining obsidian ore, the white spots on obsidian will indeed become one of the basis for speculating the quality of gems. Therefore, when buying obsidian jewelry, it is usually more appropriate to choose jewelry with uniform color and no obvious white spots.

Some people who believe in the traditional theory of health preservation and disease prevention will also pay attention to the influence of the white part of obsidian on their health. It is said that these white spots can reconcile the strong negative energy of obsidian and even affect acupoints. However, the effect of this aspect needs further exploration and verification, and don't mislead the public because of personal ideas.
