Featured japanese enameled vases anyone recognize the maker's mark?

these came up at auction a couple weeks ago but was wondering if they might be valuable.

 

Yikes! The giant hole really devalues that vase.
But they are so pretty! The blue is luscious.

 

Lovely, but I agree, badly damaged, so enormous loss of value.
If investing or buying for resale, I'd pass. If you're in love with them, bid very low and turn the damaged side to the back.

 

Might be Izumi, Nippon

 

Oh, that Blue! Persian Turquoise...?
I love it...and damage be damned!

But the design hasn't been damaged. It even seems the cloissons(?) at 10 o'clock helped preserve that area of foliage.

Too dark for Robin's Egg. The Blue of the sky in my youth, on a sunny SoCal day. Perhaps I exaggerate, but not by much. Stunning color!

What would any of you like to call it?

 

Robin's egg blue came to mind. But..... I'd say it's close to the blue of a US robin's egg, but much too intense for a European robin's egg, which is a pale turquoise with spots.

 

Is it brass or white metal? Hard to tell for sure in photos. Every once in a while cloisonné is done on silver. Not saying this is but looks like a possibility.
