Step 1Dirty ring to be cleaned
iImage Information

This is my wife's engagement ring. It has not been cleaned in several years, and I would say this is moderate to very dirty.
I'm not trying to slate your method, it just requires absolute maximum care and minimum force, which I'd hope that the people reading on here will take. I just wanted to give an extra warning.
I do it an even easier way just get yourself a bottle of Lemonade or ( in the U.S.A - soda), or tonic mixer and place the ring in the bottom of a glass then pour in until the 'fluid' is an inch past the jewellery then give it a little swirl aroun and leave for a couple of hours .
the carbon dioxide released in the fluid acts as a 'soft' acidic cleaning agent withouth damaging your ring.
Warning : do not use this method for porous stones such as tourquoise or pearl - it will dissolve and damage them.
but to answer your question yes 'Jade ' is porous - it is not uncommon to find that lower grade Jade has been bleached then sealed with lacquer or polyuerethane to give it the appearnace of older better grade JAde.
I simply use liquid soap for it all. Hold SECURELY in your hands and gently soap once under a warm running tap (faucet),-this gets any body oil off. Then do it again-you'll find it will lather better this time. Rinse thoroughly-just holding it, and dry with paper towel.
I then leave overnight on a piece of paper towel to make sure it is dry.
All jewellery stays gleaming this way,-I even wash my spectacle glasses this way too.
I can understand your method for a heavily soiled piece of jewellery, but don't let it get like that! Gleaming jewellery looks a million bucks,-even if it cost far less!!
