I think the biggest problem was sunlight. I didn't know anything about succulents. I started with these out on the porch. Then the temps got really high outside and leaves were turning brown so I though direct sunlight must not be good. So then I brought it inside and put it in the window and it seemed to do great. I think the leaves started falling off and I moved it to an area without any light. As it started dying I started neglecting it. Sort of giving up on it. So lack or water and sunlight probably caused the damage. I think maybe it is a echeveria ruffled .. I don't want to break off last leaves to see if it will root. In scared it would just be destroyed then I'm left with nothing.
