What is a geomantic stone?

Fengshui Stone: Its crystal columns in the wind are dense and grow towards the center, and their energy wants to vibrate with each other. It has a very strong cohesive effect, which can condense the main gas of the house, make it stay, and achieve the effect of gathering wealth and prosperity. But there is no divergence function, which is not enough to resist and disperse large negative energy. Therefore, when using it, it should cooperate with the crystal cluster, emit energy up and down, left and right, and disperse negative energy.
