if you go to the 2nd pic on the etsy flower . . . and then zoom in on the one you found . . . imo they're kinda close, but the 2nd one has tulle layers and the ends of the flower don't have the soft curl that the 1st pic has.
the etsy pic looks like a millinery flower/higher quality silk flower = more expensive!
edit . . . this one looks similar but it doesn't give the size . . . http://www.gandgwebstore.com/28-peon...een-tt-ea.html
