The Cullen's Crest is a family crest that was in the movies. It wasn't in the books.
Its a lion.
the Cullen crest
The Cullen family Crest is made up of: The hand, The Lion, and the Trefoil. The hand = Faith and Sincerity The Lion = Strength and Ferocity The Trefoil = Perpetuity
The Cullens each have the Cullen crest in a different form of crest and the hand symbolises faith and sencerity, the lion symbolises strentgh and ferocity and the trefoil symbolises perpetuity.
It actually doesn't say anything about a culln crest in the books but thy added it into the movie to prove they are cullens and to have a part of their family with them i guess. It doesn't exactly specify.
Because the director of Twilight, Cathrine Hardwike, thought that it would be cool for the Cullens to have something that symbolises them. The guys wear the wrist band, Rosalie wears the pendant and Alice wears the choker.
The wristband has the Cullen crest on it. All of the cullens wear this in some way. (the girls have necklaces)
Like what is it? It's this: http://media.photobucket.com/image/cullen%20crest/JoeJonasLuver12345_2008/cullen-family-crest.jpg?o=11
In the Twilight series, Rosalie Hale wears the Cullen crest as a necklace. The crest symbolizes unity and the bond between the Cullen family members.
The Cullen Crest means: The Hand- faith, sincerity The Lion- strength, ferocity The Trefoil- perpetuity. I found this in the Twilight Director's Notebook.
9 cullens
Irina did betray the Cullens by telling the Voluri that the Cullens had a vampire child.
