Interesting! Doesn't look like normal variegation to me. I would say it was caused by lack of light, but would be interested to see what others have to say about this.

Very interesting, and different than typical variegation, indeed. I would just introduce it to some stronger light and see if the variegation persists. If it does, you hit a major jackpot.

Indeed. If this is a true variegate, which it might be, do what you can to preserve all 3 cuttings. You should repot them in a well-draining soil. I've seen Jade leaves (on a cutting) go completely white when kept in the dark for over a month; didn't look like that. Please keep us updated on the progress!
