[edit]Patina on a goldring?
[edit]At Talk:Shakespeare's_signet_ring#Alloy there is a disagreement on if an old gold ring should be described as having had patina. If you have an opinion, please share (there). There's other disagreement too, if you feel like getting involved. Gråbergs Gråa Sång (talk) 09:36, 20 December 2021 (UTC)
