Kristen's New Bling. RobSten Pendant?

My affiliate, RobwardandKrisella 's readers have noticed this in relation to Kristen's new bling she wore around her neck during the Lacoste Pool Party at Coachella, April 18.  What do you think?  Is it possible that it was the same pendant/neclace Rob wore in LA for the Harry Potter - Order of the Phoenix Premiere back in 2007?  I know its a longshot lol  Thanks to Cami and Kokoika for this! And hello to Faby and Rori, too.
