the main commercial stones are all zircons of grade 4a or above. the hardness of zircon is relatively high, and it is not easy to grind or scratch, or even cut glass easily. however, the texture is relatively brittle. please avoid knocking to avoid damage. in addition, keeping clean is the key factor to keep zircon bright. if it does not shine, it must be because the surface of zircon is polluted by oil or cosmetics, if you stick a little detergent with a soft brush, it will be as bright as new.
