It seems to be too small to ID, and could have been growing under questionable conditions before you got it and that will make difference in shape and color...try taking photo from other angles and also from top, it may help.

That's how it looks from the top!

My guess is Portulaca molokiniensis, but time will tell..

Yes i think that might be it!!! Here's a photo from a similar plant we found:

Which succulent fair, may I ask?

It was one in Singapore!

Update: I pinged the seller (who doesn't know the species either!) who sent me a grown up version. It is the three shoots on the right. It seems like portulaca molokiniensis, but a specific strain...?

I don't know of any strains or varieties of P. molokiniensis available in the trade, it's not cultivated nearly as much as jades, for example.
