ID not needed to point out that container needs to have drainage hole(s) - can't tell if yours does.

It is sitting too deep inside of the pot - more potting mix is needed to set the plant higher.

Can't see the 'soil' it is in, but it could be too water retaining. Succulents need very well draining potting mix.

It probably needs much more light - the center (new growth) looks pale green and that indicates insufficient light.

It seems to be one of the Echeverias

Rina is correct. It won't last long at all as it is. Nice wedding favor though.

If you are going to start growing succulents, get a bag of cactus and succulent mix and a bag of perlite and mix 50/50. Screen out the small perlite crumbles and throw them away. Try not to breathe it. I usually use water to filter out the small bits. Have fun. You can learn a lot by reading other threads here.

Thanks for the feedback! Yes, it is in a pot in a pot, so it looks like it is sitting lower than it actually is. It does have drainage. It just made the trip from being in a cloudy, fall New England environment to now being in Los Angeles, so I'm sure it could use some sun. Thank you again for the feedback. Are we sure it is one of the Echeverias or do I need to wait for a flower to really tell?

Echeveria black knight, without enough sun maybe. Also could try for echeveria black prince??

I thought of those two, but considering the tips of the leaves? - maybe I am seeing things :)

If Black Prince (Black Knight has quite narrow leaves and is not as commonly found) it has been in really low light to get so green.
