Avoid collision with hard objects.

Although jade has high hardness, it is easy to crack after being hit. Sometimes, although cracks can't be seen by naked eyes, the molecular structure inside jadeite has been destroyed and dark cracks have appeared, which greatly damages its perfection and economic value.

Avoid dust as much as possible.

If there is dust on the jade surface, clean it with a soft brush; If dirt or oil stains are attached to the jade surface, it should be washed with mild soapy water first, and then washed with clear water. Do not use chemical degreasers. If the jade is exquisitely carved and not dusted for a long time, please clean and maintain it in professional factories and companies that produce jade.

Hetian jade is most taboo against collision.
