First of all, the quality of stones randomly placed in many antique shops must be not very good. You know, generally good jadeite has a high hardness, but if its texture is not dense enough, it is easy to fly a knife when polishing, which means that the surface of the stone will be broken because of polishing, so such a stone will generally not be polished very smoothly. Still put in water, it will cover up some flaws on the stone surface, because water can fill up these flaws and those, and every stone looks like crystal in your hand, and you can't see any flaws at all.
On the other hand, from the perspective of geomantic omen, water itself is very beneficial to the business of a shop. In antique shops, generally speaking, you need to have such positive feng shui decorations. After all, sometimes you need to pay great attention to these things that turn your fortune. If there is water in the store, it means that the financial resources are rolling in, and there will always be some clear water coming to the store to look at your goods. Decorating some stones in the water at this time, plus precious jade, will leave this good luck in the store and will not be taken away by some distinguished guests.
In this way, no matter from the perspective of feng shui or business, many shops have chosen this way of soaking water stones. On the one hand, it can attract many people's attention, on the other hand, it really supports their own business and can leave their feng shui spirit in the store. It is really killing two birds with one stone.
