First, view that with eyes to observe the surface structure of stone. In general, fine stone structure with fine texture of the texture for the best of stone products; coarse and unequal grain structure of the stone less effective appearance, mechanical properties are not uniform, the quality is slightly worse. In addition, due to the geological effects of natural stone, often produce some veins and micro-cracks, stone is most likely to rupture along these areas, should pay attention to remove. As for the lack of edges and corners is more affect the beautiful appearance, the choice should pay particular attention.

Second, the amount of stone size specifications. So as not to affect the splicing or splicing patterns, patterns, lines deformation, affect the decorative effect.

Third, that is to listen to the stone percussion sound. In general, good quality, uniform and dense internal cracks and no stone, the percussion sound crisp and pleasant; the contrary if the stone internal micro-cracks or fine veins, or due to weathering lead to loose contact between particles, the percussion Rough voice.

Four , a simple test method to test the quality of stone. Usually drop a drop of ink on the back of the stone, such as the ink scattered scattered around quickly, which means that the internal loose particles or cracks in the stone, stone quality is not good; otherwise it shows that the stone is dense, good texture.

        In the finished board selection, because the stone material is natural, can not be exactly the same texture, mining process in the level of technology there are differences,It will need granite cutting machines and wires.Most stone is graded. Granite stone without color stripes, most of the only color spots, there is a solid color. The finer the better the mineral particles.
