Isabella's cross is an item dear to Richard Alpert.
Isabella gave Richard the golden cross for him to pay her medicine with. He brought it with him on board the Black Rock, and it was briefly lost in the wreck. The Man in Black returned it to him in an effort of recruitment. Richard buried the cross after meeting Jacob. ("Ab Aeterno")

- Eko valued a very similar cross which belonged to his brother, Yemi. ("The 23rd Psalm")
