The lapis lazuli stone will get brighter and brighter if you wear it for a long time.

Specific reasons:

The lapis lazuli stone is worn for a long time, the oil absorbed will be more and more, and the luster of the surface will be more and more bright. This is because when the mackerel stone absorbs the body's oil, it will expel the impurities inside, so that the oil slowly fills the mackerel stone. Mackerel stone worn for a long time, absorbing more oil, will form a pulp on the surface, increasing the character.

Secondly, the mackerel stone in the absorption of human body oil, will be inside the impurities out of the body, so that the oil slowly filled into the mackerel stone, wear a long time, mackerel stone filled with oil, will make its texture become more and more translucent.

In addition, the mackerel stone worn for a long time, absorbing more oil, will form a layer of pulp on the surface, increasing the character of mackerel stone, but also the luster of the surface of the mackerel stone has become more and more oily, delicate and silky to the touch.
