A wind worn stone?

[Tinkercobblepot]

Can someone point me in the right direction? I would like to know what a windworn stone is used for. They go for a mint in the bazaar and they have the tradeskill tag. Many thanks

I had it wrong before. :P And btw, the Search feature on the main site is very nice for this sort of stuff. It's how I found this.
