Jadeite and nephrite jade…are the jade found on the HSN worth purchasing?

I would say that the only jadeite or nephrite worth purchasing, not just on the HSN, but anywhere, is natural untreated jade. Or as it is called in the industry…Grade A…the grade has nothing to do with the esthetics of the piece, it only has to do with weather or not it’s been treated. A grade= untreated B grade= dyed or impregnated with polymers etc…C grade= multiple treatments, typically color dyed, and impregnated with polymers. Natural grade A is the only jade worth collecting. That’s my opinion. And sticking to it.
