Identification: Succulent ID needed, please :)

Hi, I have bought succulents from a garden center, but they were only called succulents and that's it.
Does anyone know the exact name of this one? I have two more, but they are at work and will post the pictures another time.

 

most probably a type of crassula. it's a LARGE family...

 

Looks like Crassula ovata 'Gollum', Trumpet Jade.

 

That's the one! Thank you!
I wish all garden centers would name their plants properly, but now mine has a name, many, many thanks! :)

 

Definitely Crassula ovata 'Gollum'

Crassula is a genus not a family.
