Pearl

[Organically Maz]

I have no idea what the item Pearl does and I don't know if I should sell it

Yes I went onto the wiki, it gave me no results

before the fish pond update you were only allowed to get one - it was just a fun item. I would just hold on to it.

In general, hold on to everything that's not a crop - i keep at least 10 of each crop, foragable, or fish just in case i need it later. This proves well with fishing ponds, I have 16 of them going at once so i always need random things to keep them growing

I've been holding onto my pearl also.

Actually that's not true, only one was easy to get through the Mermaid show, but you could get extra pearls when fishing in the submarine. The drop rate is very low though (0.417967776% according to the wiki).

1.4 added two more ways to get one, a dialogue with Willy if you have full crab pond and artifact troves (the wiki doesn't give numbers but it's most likely another very low rate, though it can be predicted with Stardew Predictor).
