They botched the editing of the jewel-nabbing scene quite a bit. Olenna adjusts Sansa's braids, plucks the jewel with her right hand, directly moves it to her left hand - then it cuts to a camera angle from behind her, showing her left hand resting on the table, clearly not holding anything. A couple of seconds later, after Tyrion arrives, she again moves something from her right hand to her left hand, and then it looks like she is pinching something between her left thumb and long finger (her index finger is poking out, the rest of the fingers tense). And then there are a couple of weird cuts where the camera is from her side, with her right hand on Sansa's shoulder, and from her front, with both her hands down by her waist. It cuts back and forth a couple of times, instantaneously. They obviously did at least two takes and edited them together, missing that they were slightly different. That could definitely confuse people.
