Ok, so here is how I did this..
First I took a picture of the rose inside the jar.
To make the rose stand I used clay
Then I started editing out the clay
After that, I added the sparkle or fairy dust (I'll do a separate tutorial on that)
After that, I added the pink "glow"
to do that, I drew with a soft brush, gave it a really high gaussian blur
(blurred it 3 times)
then set the blending mode to screen
Then the final touches..
and voila !
