Black stone hearts are dropped by monsters in The Shadow Reef.

100 of them are required to make each of the undead slayer ability codex, dragon slayer ability codex, and demon slayer ability codex, alongside 2 cut onyxes and 60 oceanic components, resilient components or silent components, respectively. The ability to do so requires level 88 invention as well as purchasing the ability to discover the blueprints from the Elite Dungeon Reward Shop run by Bryll Thoksdottir at Daemonheim for 100,000 dungeoneering tokens each.

Prior to the removal of the sigil slot on 19 August 2019, they were used to make the sigils that correspond to the ability codexes that are now in-game.

25 of them are also required alongside 5 cut onyxes to convert a Ring of death to a Ring of death (o). This can be done by speaking to Death in his office after purchasing the ability to upgrade the ring from Death's Store for 150 reaper points.
