Will licking authentic jade cause your tongue to go numb?
I was flipping through the channels on TV this morning and I caught a small bit of a local show, and there was a woman talking about buying jade jewelry. When explaining tips for spotting fake jade she said that real jade would cause your tongue to go numb if you lick it. I can’t seem to find anything online verifying this… but maybe a jelly knows. Is this true? And if so… why?
