First of all, you have to understand the composition of salt crystal lamp. Among them, 98% is sodium chloride, and the remaining 2% is more than 80 kinds of trace elements and minerals necessary for human body, so in terms of color. The richer the content of trace elements and minerals, the better the grade. So how to judge whether trace elements and minerals are more or less? It depends on the color. The darker the salt lamp is, the higher the content of trace elements and minerals, so when you choose the salt lamp, the darker the color, the better. This is the same as the greener the jade.
Then you should pay attention to whether the texture of the salt lamp is too natural and whether there is a fault when choosing it.
Finally: in fact, people and salt lamps should talk about fate. When you choose the salt lamp, the salt lamp is also choosing you. If it's destiny takes a hand's person, I will definitely choose my favorite salt lamp, which is very spiritual! !
