Which is better, white crystal or obsidian?

Obsidian is more precious than white crystal and carries a purer and more powerful magnetic field.

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.

White crystal is in season. We usually call opaque time, while transparent crystal is called white crystal. White crystal is one of the seven treasures of Buddhism. As the name implies, it has a strong positive energy to offer Buddha, ward off evil spirits, block the brakes and house, and has a strong effect of eliminating negative energy. White crystal is colorless, clear and transparent. White is a combination of all colors, such as red, orange, yellow, green, blue, indigo and purple, representing balance and happiness.
