Q for Queen
The Q in this picture stands for Queen. The diamonds represent JonBenet being valuable, just like diamonds, to her parents. They are also precious gems, which also describe JonBenet. She was a precious child, who was a gem in the beauty pageants. Not any child could be put in beauty pageants at that age and win. The Q is connected to clip. I imagine the Q being connected to her mother's bracelet, but it is alone now because JonBenet is gone.
