Aww, Thanks for the Acorns Ursula
Since I got 10 acorns, here is a trivia from my side; I love that one and the first time I saw it, I call it "BCC", Bacal Cells Crassula, due to the unique pattern. The embossed spots are random at the center, but they are tidily arranged palisading at the margin along with those tiny teeth. That palisading pattern is unique to some skin tumors if observed under microscope especially BCC (Basal Cell Carcinoma)

They are not striking, but they're there, (or am I seeing things...?
)
Of course no one else calls this Crassula BCC,
but I hope the trivial details will make you love it even more, Sorry for bringing up non gardening things, but I can't help it... I do not want to hallucinate seeing things alone..
Thank you again for the acorns and discussion
