I think the gold band Kristen wears is from Robert (I think the necklace she wears is from him as well). I notice that Kristen changes the hand she wears the gold band on (most likely to keep people guessing about it). Either way this gold band Kristen wears means alot to her and I am glad she wears it. I think Kristen is very sentimental; notice how she had Rob's beanie hat in Australia (how sweet). Kristen and Robert make a good couple and I wish them lots of happiness.
