The difference between black tourmaline and obsidian

Black tourmaline is a dark to pure black opaque tourmaline, usually a variety rich in iron or titanium. Obsidian is a common black gem, mineral crystals from volcanoes, also known as Longjing, Shisheng stone, etc., is a kind of naturally formed silica. Let's take a look at the difference between black tourmaline and obsidian.

The difference of composition between black tourmaline and obsidian

1. Black tourmaline: black tourmaline is a member of tourmaline minerals, which is actually black tourmaline rich in iron. It is a complex borate, a crystal mineral, often occurring in the contact zone of granite, and in crystalline schist, gneiss and phyllite affected by gasification.

2. Obsidian: obsidian is formed after the magma flowing from volcanic lava is suddenly cooled in water. The magma outside the lava flow cools and condenses rapidly when it encounters sea water, and the crystal structure does not have enough time to grow. A kind of natural glass formed by the rapid cooling of magma, which is an impure crystal gem and its main composition is silicon dioxide.

The difference between black tourmaline and obsidian

1. Black tourmaline: black tourmaline has piezoelectric effect and thermoelectricity. When heated by friction or sunlight, it will produce a magnetic field that absorbs dust or debris around it. Therefore, it is often processed into some handicrafts, such as black tourmaline bracelets, black tourmaline pendants and so on.

2. Obsidian: obsidian can be processed into handicrafts. Because of the characteristics of glass, the broken section shows a shell-like fracture, which is very sharp. In ancient Stone Age, obsidian was used as cutting tools such as knives and arrowheads. Modern people use obsidian to make surgical scalpel blades.

The difference of efficacy between black tourmaline and obsidian

1. Black tourmaline: the magnetic field produced by black tourmaline can promote metabolism by affecting water molecules in human cells, and the tiny magnetic field can also regulate the bioelectricity of the wearer. restore the bioelectrical disorder caused by local pathological changes in the wearer's body to normal, so as to keep the wearer healthy. Finally, the magnetic field of black tourmaline can also protect against irritability and insomnia caused by electromagnetic waves in modern society, while helping the wearer to protect against harmful radiation.

2. Obsidian: obsidian can extremely ward off evil spirits and dissolve negative energy. among the Buddhist relics in ancient China, there are quite a lot of obsidian sacred objects or Buddha statues about calming houses or repelling evil spirits, because of their powerful and pure energy. therefore, it can be placed in a place with heavy evil spirits, and even made into a black Yao Buddha statue, which is even more effective in avoiding evil spirits, and it is also the best gem for Buddha to practice and give alms.

Conclusion: the biggest thing obsidian and black tourmaline have in common is that they are black, but obsidian usually has a rainbow eye effect, while black tourmaline is pure black, while obsidian is black but not black.
