odd find (slate)?

[Moe (fl)]

Found this item at the beach last week. It was just lying near the high tide mark. It caught my eye because it looked different than shells and it is blue!

It feels heavy and there is no metal. I placed a quarter for size reference. It does not look to be from Florida. Looks like blue slate but am not sure.

Any ideas?

HH!

How did this Kyanite piece get to the beach in Florida?

Maybe someone dropped it.
