Finnish ring size conversion


#1

Hi,

I have a customer from Finland who bought one of my rings. The ring
size she specified is 17. I am not sure which scale they use in
Finland, German or Swiss. Does anyone know what size would that be
in USA or UK sizing?

Best wishes,
Lilia

Oh. The mushy mandrel says that’s between a size 6 1/2 and 6 3/4.
