Knowing a little bit of jade knowledge knows that the chrome in jade determines the green level of jade. We often feel that green will become longer, especially jade bracelets, necklaces and items, such as jade bracelets, necklaces and items that can be worn against the skin when worn. And what is the reason for this?
The more scientifically based explanation is that the human body has temperature, and when the human body perceives heat, people sweat, and through the micro-cracks of jade jewelry, the acid and alkali components in the sweat will penetrate into the jade. It then dissolves the chromium ions in the jade that are already in a fixed state, causing changes in flow and migration; or these chromium ions produce chemical effects. In the long run, the naked eye will observe that the green color of the jade will become larger. And in addition to the green changes, some jade jewelry patterns will change, but the overall value will not change.
