I think Dev probably wrapped up Kaju's moms necklace for her and gave it back to her as her b/day gift....
....b/c, he knows how much it means to her, and how much it would mean to her that he gave it back to her on her birthday...
soooo, I think its the perfect opportunity for Devu to do something special for her...
Aur I hope that Dev is smart enough to think of something like this...unless of course he wants to keep it and give it to her as a shaadi ka tofa on the night of their wedding....
