I'd guess it's got Graptopetalum paraguayense in it, if indeed it isn't that very species of plant. From guessing, it looks a little too round to be pure, but it could be. Flowers would tell.

ETA - it's a hybrid, maybe of Graptopetalum p. and a species of Pachyphytum, or Echeveria, or Sedum, to name three.

Thank you! I’ve recently upgraded my collection with a new grow light, so I’ll see how it progresses!

Well I think it’s Graptopetalum pentandrum ‘Murasaki’;).

Jena,

Yes, as they get larger they'll be easier to identify. The next five to six months are prime time for most of the New World Crassulaceae (and the Old World ones, too) to be growing, so you should shortly be seeing postive changes, as the old leaves shed and the new ones grow.

It could be as Kara said, Graptopetalum 'Murasaki', a hybrid of G. pentandrum and another Graptopetalum species.
