Help with another couple of unknown marks, impressed this time

So I was on a bit of a roll today at the charity shops, also picked up this lovely, gilded dish with what looks like an impressed crown, could be English or European - unfortunately I can't get a clear photo of it, but someone might have and idea
, and a Ruskin-like glazed pottery vase with an impressed shell type mark. Any ideas appreciated. Thanks in advance.

 

The third photo down just looks like a smal glaze skip to me - not a maker's mark.

 

Hi, no, no glaze there at all, definitely an impressed mark - looks a bit like a scallop shell

 

Oh sorry, are you talking about the rose bowl, not the pottery vase? Yes, you could be right I did wonder, but it does have a very definite shape to it, like crown points, just very hard to photograph as it's quite shiny. thanks
