Is this original Delft?

Hi

Can anyone shed some light on this plate please? Is it original Delft blue or something else?

Thank you.

 

Think the mark is upside down and might be an "R" in a diamond pattern. Had a quick look through my books but still can't find it.
Edit...
There is a lot of discussion about "blue R in diamond pattern" here.

Scroll down to see the discussion.

 

I don't think any of the marks they show are the same.

 

Updating this thread with better images of the R in a diamond and the plate itself. Can anyone help identify please? Also what is the best way to remove the metal hanger, do I literally prise it off? Feels fragile and risky!

Thank you.

 

I would cut the wires so the hooks can just fall off

Untie the wire and it will relax letting you remove them.

 

Hi
This is certainly not genuine Dutch Blue Delft. Early Delft is earthenware with a tin glaze.
Your plate is of a hard paste body and the pattern is printed. As to the mark, it certainly is not of any Dutch Delft stable i have seen. Also, note English Delft is also earthenware which has a tin glaze. Use long nose pliers to snap one section and then the rest falls away.
Good luck

Thank you... if I could, I'd rename this thread to "R in diamond stamp" I can't find the maker..
