In a large bowl, sprinkle unflavored gelatin over 1 tablespoon cold water. Let stand for 1 minute. Add boiling water and raspberry gelatin. Stir for 2 minutes to completely dissolve. Stir in remaining cold water. Refrigerate for 45 minutes or until thickened. Place 2 1/3 cups cranberries, apples, and oranges in a food processor, and pulse until chopped. Transfer to a bowl. Stir in sugar. Stir into thickened gelatin. Fold in the nuts, celery, and remaining cranberries. Pour into a 10 inch fluted tube pan or an 8 cup ring mold coated with cooking spray. Cover and refrigerate until firm. Unmold onto a platter for service.
