Do you dare to buy local red corals when you travel to Taiwan Province Province? Two days ago, a friend sent me a photo of coral, which he bought while traveling in Taiwan Province Province five years ago. He said that his coral ornaments were not as bright as before, and they felt foggy, and then the colors were not as bright as before.

However, judging from the picture, it can be defined as Sardinia, which has a relatively large output, and its color is relatively poor in Sardinia, but what I want to tell you here is that coral is an organic gem, and the sweat and metabolites secreted by our human skin are actually acidic.

Relatively speaking, organic gemstones are not resistant to acid and alkali corrosion, so when we wear organic gemstones such as corals and pearls, we should try to avoid direct contact with them. Try to wear it outside the clothes. Another thing to note is that if we wear jewelry on our hands, we should try to take it off when washing. Do not touch acids and bases.

However, although it will lose its luster when it comes into contact with acid and alkali, and its color will not be as bright as that bought before, as far as corals are concerned, the later polishing and maintenance can still be restored to its original state, but this polishing and maintenance actually has certain losses for corals.
