I love variegated Gasterias. Not sure which one this is, but it's a beauty!

I wanna suggest G. negricans, but it's really a WA Guess. I may have had it, but as no ID at some point.
Yes, you're right Karen! I used to have it too, now that you say the name. Looked it up and sure enough: G. nigricans marmorata. One down, two to go!
