Sam 2- What you posted about the Gra -I didn’t find on that page.
I spent some time researching this and I’ll try to give a Short synopsis. The Gra explains the Mechaber is holding like the Sifri which is quoted by the Chocmas Odom.
The Rema brings a Mahrik that argues based on Reshonim.
The Gra argues about this idea from the Mahrik – that you need Pritzus along with the clothes being created for Avodah Zorah. He holds that if the purpose of the clothe was created for A’Z -it’s always Ossur, but if Stam Azoi then it would be Mutter.
The Nosai Keilim have problems with this Mahrik & knock down one Raya.
To conclude, when it comes to something like Nose-rings, the Gra would hold like the Mahrik that this wasn’t created for A’Z and would probably be Mutter.
But I believe the Chomas Odom is Paskening like the Mechaber that the Issur is copying the Goyim on everything, not just things created for A’Z. The question is Why? I think he didn’t want to Pasken like the Rema because of all the problems with the Mahrik.
So we probably have to follow the Chocmas Odom because he is Basroh. So it would come out that Nose-rings are Ossur from the Torah!
