    A view
    Observe the surface structure of the stone with naked eyes. Generally speaking, the stone with uniform fine structure has delicate texture, which is the best stone; the stone with coarse and unequal grain structure has poor appearance, mechanical properties and poor quality. In addition, due to the influence of geological process, natural stone often produces some fine veins and micro-cracks in them. Stones are most likely to rupture along these parts, and should be removed. As for the lack of edges and corners, it is more beautiful and should be paid attention to when choosing.
    Two quantity
    Size and size of stone. So as not to affect the stitching or resulting in splicing patterns, patterns, lines deformation, affect the decorative effect.
    Three listening
    Listen to the percussion of stones. Generally speaking, good quality, compact and uniform interior and no micro-cracks of stone, its sound is crisp and pleasant; on the contrary, if there are micro-cracks or veins in the interior of the stone, or because of weathering resulting in the particle thixotropy, then the sound of knocking is coarse and dumb.
    Four test
    A simple test method is used to test the quality of stones. Usually a small drop of ink is dripped on the back of the stone. If the ink is quickly dispersed and leached around, it means that the particles inside the stone are loose or there are micro-cracks, and the quality of the stone is not good; otherwise, it means that the stone is compact and of good quality.
