Yes, you can start your Pachyphytum from a stem cutting. Ideally one with a healthy rosette (a few leaves and the growth center intact), with just a bit of naked (leafless) stem at the bottom, like no more than half an inch or so. Wait a week after you take the cutting to pot it up (and use a relatively small pot, because you can upsize later after it roots and takes off). Wait another week after you pot it up to water for the first time.
I would recommend when you take the cutting you simply remove the bottom leaf or two to expose that half inch of stem, but save the leaves and put them on top of the soil in another container, just to watch the process of leaf propagation unfold. It's a delay of maybe 3-6 months relative to starting from a cutting.
This may not be the best time of year to be propagating this plant, if you are in the northlands, what with the cooler/darker months already upon us. You will get the best results when there is ample light and warmth, in terms of rooting and growing and especially good form.
