I will tentatively say an Echeveria shaviana?

After looking around at Echeveria Shaviana, I can see the resemblance. Minus a few subtle differences. But so far, that looks like it might be it.

I am 100% sure it is an Echeveria, but I tell you! These hybrids! Sometimes it is impossible to tell for sure what it is...

Agree with Chris on being an Echeveria 'Neon Breaker'. Could definitely use more light. Acclimate slowly to the sun you don't want to burn it:). Here's mine. Mine gets probably too much sun for it's liking. He's all curled up;).

Mine lost the green inner leaves and turned very purple under my LED grow light in the basement last winter (above, no filter). Now it is back to normal under the sun.

Very Cool!

I miss the pretty purple on mine:(. There's a little, but not like when I first got it. Like I said I think it's getting too much sun and not enough water. So it's in full on stress colors now. Still pretty tho.

Chris- is it just my imagination but do LEDs turn your plants more purple instead of for example pink? I don't use lights. Everything is outside:). I swear when I see people's succulents that have been grown under LEDs they have this cool purple hue.

Tristan if you give yours more light your plant will loose all that colorlessness in the middle, and gain pretty color:). That's just from lack of light. I just bought an Echeveria from Home Depot that has the same issue.

Kara, different plant behave differently.

My aeonium kiwi became dull late fall due to lack of light but became this beautiful tricolor look after 24 hours of continuous, close range exposure.

The two aeoniums turned from light green to this:

Same plant as above without filter.

It has retained the purple color with more green center under the sun.
