Bella Swan's Cullen Crest

In Twilight, i though the Cullen Crest was a really good visual way to portray a tangible link between the Cullen's. To unify them as a family, even though they aren't blood related. Later, i discovered it was just something that they used to market products to the fans. However, i think that it's really symbolic for Edward to give Bella a Cullen Crest ring, as a metaphor for official joining the Cullen Family. I love it. However, i wouldn't buy this, as I'm not going to spend money on stuff that is useless and only being sold because it has Twilight printed on it. But, it's still cool for the films!! Love it!
