The so-called obsidian is actually acidic volcanic glass-that is, there are often many small bubble inclusions in natural glass obsidian, and the inside is in a flowing structure. But because the color of obsidian is too dark, I'm afraid you can't see it without a strong flashlight. But if you have a strong flashlight, just use it to illuminate Obsidian. You will find that the color of obsidian is not black, but dark brown or dark brown, and then you can judge that it is obsidian. Because there are not many kinds of gems similar to obsidian, such as coal essence (nearly half lighter than obsidian) and black agate (opaque, while obsidian is translucent-transparent). Obsidian is extremely evil, which can effectively resolve negative energy. Among the ancient Buddhist relics in China, there are quite a few obsidian relics or Buddha statues about town houses or exorcism. Obsidian is also the best gem for Buddha to practice and give alms. In the crystal family, obsidian is also one of the crystals with the strongest negative energy. Obsidian is very cheap, but there is no way to answer your question specifically, because the price varies with the quality according to the size of the beads. Obsidian is a kind of high-energy gem, but it is cheaper because of its large output. For me, the cost is around 100- 150. He spent a lot of time earning more (after all, the beads he chose can still be sold as long as there are no big flaws ~ ~). Crystal power is really understandable. If you believe it, it's gone ~ ~ I like obsidian best ~ ~ At present, there is an obsidian arowana necklace ~ ~ I feel much more at ease after wearing it ~ ~ Who makes it the most powerful ~ the most exorcism ~ ~ plus disaster prevention? When a volcano erupts, it is sent to the surface of the earth, also called "volcanic glass". It has powerful and pure energy, which can eliminate the inherent obstacles, strengthen the human body's ability to lower the plate, prevent evil spirits from taking advantage of it, and has the functions of stability and sedation, helping people easily enter the depths of consciousness, calming people down, and improving schizophrenia and bipolar disorder caused by the extremely unbalanced secretion of chemicals in the brain. Balance the energy of extreme yin and yang and make people live in harmony.
