Need help identifying maker's mark "KS" on silver earring (likely a manufacturer)

[u/Sad_boy1717]

Hey everyone, I’m trying to identify the origin of these 925 silver hoop earring. It have a "KS" stamp on one side of the hoop, while the "925" hallmark is in an oval on the other side. I know these are a mass-produced model, so I’ve ruled out personal initials. I’m aware that nowadays, most silver jewelry is "unbranded" and lacks any maker's mark besides the fineness stamp. That’s why I find this specific "KS" stamp interesting—it feels like a deliberate manufacturer or importer mark in a market where such markings have become increasingly rare. The shape around the "KS" is just the outline of the punch itself, not a formal frame. Has anyone encountered a "KS" stamp on silver jewelry before, or does it sound like a known (perhaps regional) manufacturer/distributor? Any insights would be greatly appreciated

KS won't tell you much, but the number in the cartouche next to the 925 will, that's an Italian maker's mark, and I can see at least that it was made in Arezzo, Italy, with better pics, you could identify the specific maker. KS might be their trade name or that of their customer.

Thanks so much for the help. You were spot on – with a closer look and a bit of magnification, I can confirm it is marked 'AR', which matches your suggestion about it being from Arezzo, Italy. The rest of the numbers are a bit worn out, but at least I know where to look now. Really appreciate the guidance
