The quality of processed finished decorative stone can be distinguished from the following four aspects:
At first glance, it means observing the surface structure of the stone with the naked eye. Generally speaking, stone with a uniform fine material structure has a delicate texture, making it an excellent choice for stone; The appearance effect of coarse-grained and uneven-grained stone structures is poor. In addition, due to the influence of geological processes, stone often produces some subtle cracks, and stone is most prone to rupture along these areas, so attention should be paid to removing them. As for the lack of edges and corners, it is particularly important to pay attention when choosing.
Second quantity refers to measuring the size specifications of the stone to avoid affecting the splicing or causing deformation of the patterns, patterns, and lines after splicing, which may affect the decorative effect.
Three listens, that is, listen to the sound of stone tapping. Generally speaking, high-quality stone has a clear and pleasant knocking sound; On the contrary, if there are slight cracks inside the stone or if the contact between particles becomes loose due to weathering, the knocking sound will be rough and hoarse.
Four tests, which use simple testing methods to test the quality of stone materials. Usually, a small droplet of ink is dropped on the back of the stone. If the ink quickly disperses and leaches out, it indicates that the internal particles of the stone are loose or there are gaps, and the quality of the stone is poor; On the contrary, if ink droplets remain in place, it indicates that the stone has a good texture.

1. The stone has a radioactive qualification certificate. Please request it from the dealer when purchasing. Do not purchase without certification, and be careful to choose A-class products for home decoration.
2. When choosing marble and granite, marble should be the first consideration. Under normal circumstances, the radioactivity of granite is greater than that of marble.
3. In general, the consideration of stone should be black, gray white, flesh red, green, and red. From the perspective of radioactivity, from high to low, the order is: red>green>flesh red>gray white>white>black, basically in this order.
