An Albumen Pearl is a type of trade commodity in No Man's Sky. It can be found on planets , or moons, within a plant pod (after the pod is opened, the pearl illuminates). Albumen Pearls can be bought and sold at a Galactic Trade Terminal or NPC traders for Units.
Similarly to Gravitino Balls, interacting with the Pearls causes the player to immediately receive a three-star wanted level. When harvesting from plants that you have grown yourself you do not gain a wanted level.
