Hard to tell from the pic and it looks more green than blue. Just by the shape of the leave, maybe Echeveria 'Black Knight'. Do you grow this indoors year round? Echeveria 'Black Knight' will become a dark purple in full sun, so I'm not sure exactly what it might be. For sure an Echeveria or possibly x Graptoveria.

Looks like Echeveria agavoides to me. The leaves should not be pointing downward, though. Perhaps because of transplant or not enough light?

Looks to me that it was grown in insufficient light. Gradually acclimate it to full sun.

That soil should be cut by at least 50% with perlite / pumice - it doesn't provide enough drainage the way it looks now.

I like that pot.

Rosemarie has it again, folks! And at second look does look like an agavoides
