Finely chop the orange in a food processor. Combine cranberries and sugar in a heavy saucepan. Cook and stir over medium heat until cranberries just begin to pop, about 10 minutes. Transfer cranberries to a bowl, add apricot preserves and mix until melted. Stir in chopped orange, drained crushed pineapple and lemon juice. Cover and refrigerate until well chilled.
