More hallmark help please!

Scrap ring but I don’t recognise the marks (and I’d like to learn before it goes on its way)Not unusual as unless they are idiot proof UK ones I’m a bit clueless.
Ring looks to have gold shoulders but I haven’t tested it yet.
31 and 32 scratched either side of the stamps.
Sadly I don’t think the ‘Simone & Ricky’ worked it out as Mr & Mrs!!
Classy ring....not

 

Have you tested it for silver?

 

Yes. Good reaction with 18k acid. Shoulders test as very strong to 10k, fading slightly but still good at 14k and gone at 18k.

 

You've a 31 mark as well, upside down, with a European 1 fwiw.

 

It looks like Simone Ricky is one person and MR is another.There appears to be a lot of casting porosity or solder on the shank.

 

Those stamps are bugging me because I can’t track them down. Googling a crown hallmark and Z is too broad a search!.
