I just replayed the scene. Chill reaches for them at the last second. He clearly tugs on them, and then you can clearly hear (just listen, it's apparent if you have a decent sound system) the jewels shower on the pavement. The iconic shot of the pearls scattering the air that was in the Burton film is not here. But if you look closely, you can see some of pearls near where he fell, and, in the next shot, the jewel's are no longer around his wife's neck. I don't think Chill actually took the necklace, so maybe Bruce repaired it.
