I can't help with ID but it's a beautiful plant. A few things to keep in mind which holds true for MOST succulents, keep in mind this is not all. Most want about as much sun as you can possibly give them, this means outside when/if they can be simply because lower light outside is better than bright light inside. When moving it into the sun be sure to do it gradually over a period of time so you do not sunburn it.

All succulents I know of prefer very well draining soil which means very little to know peat based soil types. If you are using a peat or coir based soil (most anything you buy ready made at a store) then add AT LEAST 50% perlite or grit to the mix.

Your plant shows signs of being either over or under watered. My guess would be over watered since love is the #1 killer of succulents. If you never water your plant then a bit of water will perk it up, but if you water it too much then you'll need to pull it from the pot to be sure it isn't starting to rot. Also the pot inside a pot is not the best way to go, especially if the outer pot doesn't have drainage holes because water will collect and cause big problems.

Again, I'm sorry I can't help with ID but at least this will get you started. Someone I'm sure will be along shortly with a positive ID and better instruction for this specific plant.
