Hi all, I've just noticed what looks like copper banding on some sterling sheet I've received (not from Cooksons). It looks as if maybe the copper and silver did not mix properly and then once the stock was rolled it gave the sheet a banded pattern. Attached is a quick picture with my phone.
I've had this material for around 3 months and only noticed it now so I'm not sure if some of the material started to oxidize and therefore show up more.
I haven't touched base with the company yet as they're customer service lines are closed.
Has anyone ever seen this before? I'm concerned that if it is indeed copper its going to impact wearability (ie finger turning green etc).
