1. Whether to put stones at home depends on what kind of stones they are. If it is a natural mineral gem, it is better to keep it at home, such as crystal, agate and obsidian. These natural stones are auspicious in geomantic omen. If it is placed in a place with good feng shui, it can improve the fortune of the whole family and also have the effect of exorcism, so it is more suitable for home.
2. If it is an ordinary stone, it can be placed at home, but when the water chestnut is distinct or grotesque, it can't be placed at home, which may lead to changes in feng shui at home and affect your fortune. If it is a round stone, it can be kept at home.
