Really white Pearl and Jade?

Hi! So i have a question,

I have 4 Pearl and Jade motherplants, I can often snag clippings from them, but they have never produced something like this for me before. The variegation of white has never been so pronounced and in your face! This clipping has been growing for a few months in a greenhouse cabinet under constant grow light, and this is the only plant like this. Any ideas what might have happened? She is absolutely stunning don't get me wrong! But none of my other clippings have produced variegation like this. Still kinda new and learning the hobby so any advice would be greatly appreciated.

Thank you!
