Compared with other kinds of jewelry and jade, lapis lazuli has lower hardness, so it is easy to be scratched by some sharp objects. Therefore, when we wear or store lapis lazuli, we should avoid contact between lapis lazuli ornaments and other metal ornaments, so as to avoid collision and scratch lapis lazuli ornaments. Of course, when storing lapis lazuli jewelry, remember to put it in a relatively safe place, not too high, and don't put it with some sharp metal tools and other jewelry.

The sparkling mineral in lapis lazuli is natural copper, and we all know that copper is an easily oxidized substance. So if you want to maintain lapis lazuli, you must avoid oxidation. As for how to avoid oxidation, the most basic point is not to put lapis lazuli in a place with water, and secondly, not to let soy sauce, coolness, oil stains and other stains come into contact with the surface of lapis lazuli. It is even more difficult to release green gold in some solutions with higher pH value. Once all kinds of water stains appear on the surface of lapis lazuli, you must remember to wipe them off immediately.

Finally, I need to remind you that the most basic maintenance of lapis lazuli is to do a proper cleaning. Remember never to wash lapis lazuli with water, because lapis lazuli is composed of many minerals, and there are various tiny cracks in its internal tissues. If lapis lazuli is soaked or washed with water, it is easy for some stains to reverse osmosis into lapis lazuli. The correct way is to wring out the water and wipe the stains on the lapis lazuli surface with a wet towel. You can also gently wipe it with a soft brush.
