Big Jewelry-particularly bling, as some may refer to it, seems like it is here to stay. With no decline of decoration pieces looming on the horizon, it seems that we can now coin items like giant necklaces "investment pieces". If I am sinking the dough into an item, my pick would be this Theo Fennell cross. I like the size and chunkiness, but most of all I like the diamond-encrustment. As they say, diamonds are a girl's best friend.
