Dan Flood Photography – Unknown Necklace Needs Identification

I came across this picture today and I liked that necklace so much I had to post it! I’ll need your help on it because I have absolutely no idea where it’s from and even if I won’t get to buy it instantly, at least I’ll know what design stole my heart in an instant.

It’s a picture signed by Dan Flood and I believe it to be for an advertising campaign. Which one?
