Please test it first to make sure its legit 14K. There’s a ton of counterfeit plated gold “made in Italy” chains out there. If it tests correctly then you can try and identify the stamp but IMO it’s unlikely that you’ll identify it and IMO it doesn’t matter. The important Italian companies use 18K.
IMO if you’re selling it, all you need is Made in Italy 14K Gold Box Bar Link Chain and the weight.
If there’s a specific name for that chain type others will post.
