Does Esme and Carlisle wear a piece of Cullen Crest jewlry? (in the movie) o is it just the "kids"?

but how come tu never see them like Rose, Alice, Ed, Em... and what about Jasper??? i've never seen him with one either. even though he is a Hale, but still Alice wears one. im confuzed!

If tu look in the deleted scenes on the Twilight DVD Carlisle is wearing his in that one and in the cocina when Bella is first meeting the Cullens Esme is wearing hers. tu see Jaspers in the baseball scene as well as Carlisles.
