Unknown 925 ring with Cursive Mark

[Angela.Buchan]

I have no idea how to read this cursive. I’ve searched the upside down version of this picture under “W”s with no luck. Is the first letter a T or F? Etc. Does anyone know what the initials are or maker?

It may or may not help but I see this as 'Ns'?
