Well… not actually missing.

I noticed this in a few of the photos and can now confirm the reasoning behind it.

Obviously hospitals are meant to be kept as sterile and clean as possible… therefore washing your hands is something you must do over and over and over again.  This is why her very famous engagement ring was removed.

A palace source told People magazine:
“The plan was always to take it off when she went into the ward in the same way the Duke and palace staff rolled up sleeves and tucked ties into their shirts. They revealed that William’s jacket and Catherine’s clutch were left in the care of hospital staff while they were given a behind-the-scenes tour of the Oak Centre. And before their audiences with young patients, they followed strict hospital protocol by rubbing antiseptic gel onto their hands”.

At least now we know her LK Bennett Natalie clutch is not only stylish, but practical!
I wonder what else she keeps in there?!
