The diamonds appear when you status is green and unchanged since X time (can't remember exactly how long).
The difference is time related (the files are called green.gif for the diamond, and green-recent.gif for the smile, it's self-explanatory i think)
i'll come back if i can find what time needs a green smile to become a green diamond.
