Diamond on Isla Perdida

[Cursed_Kitten]

Hey fellow Pirates,
I have seen forums for this topic, I even followed a series of screen shots to try and find it. But it seems impossible for me to find the diamond.
I am not sure if they have moved the spot, or if I am just walking inches by it, but it is getting so frustrating!
I know people have gone on some sort of walk along with others who show the exact spot.
Does anyone know where to find those sort of people who do that?

I'm almost always on Lempona Ocean, and my name is Charlotte Foulshot.
Thanks for any advice and help you may give me.

Anyone at all?
