Possibly Graptoveria ‘Fred Ives’

Maybe Graptoveria ‘Debbie’?

Possibly not Fred Ives - those have differently shaped leaves, not so narrow at the base, and less of them. They are also somehow concave and keeled - but in unsufficient light, rosette could be quite flat. And, unless recently beheaded, Fred Ives usually grows longer/taller stem, that is thick and has darker scars where older leaves fell off. They tend to have rosettes on end of trunks, with rest of it 'naked'.
