If it is determined that this jade is jadeite, then I suggest that the landlord can purify this jade by degaussing the crystal. That is, jade can be soaked in mineral water for one day and one night, or washed directly under tap water for 20 minutes; You can also take it with you when you go to the temple for incense purification. Wear it after purification. If it is still cloudy, it is recommended not to wear it again. It may not be suitable for the landlord.
