Now the stone market is in chaos. Many businesses will sell artificially colored natural stones. Here’s how to distinguish them.
- The colored stone is bright in color, but unnatural and has no color difference. From the section and bottom, the colored stone is black as a whole because it has been soaked, while the front section and bottom should be white gray.
- The gloss of colored stone is generally lower than that of natural stone.
- Stones coated with wax to increase gloss are baked with matches or lighters, and the surface loses luster and shows its original appearance.
- At the notch of the plate, a layer of coloring penetration can be seen, with deep coloring on the surfaces on both sides and shallow in the middle.
- Colored stones coated with oil to increase gloss have a sense of oil stains on the back.
- The coated colored stone has high gloss, but the film is not strong enough, easy to wear, and there are scratches when looking at the light.
- Colored stones are domestic stones with loose stones, large pores, and high-water absorption, which can also be distinguished by knocking.
