Jade pieces are brittle and will break when hit with hard objects. Make sure that you take off your jewelry before you go swimming in a pool or hot tub. If you’re handing dirt and soil, quartz dust in soil is abrasive to the stone. Avoid cleaning your jadeite with any acids or alcohol! It is suggested to only apply water or water mixed with mild soap to get it nice and clean.  [/other]
