Guys, Why would you give a girl a ring? If you aren't dating. Symbolic?

The problem is he gave one to my sister. 🀣I was in his shop and talking to my sister about how I lost a ring.

Then I turned around and he said he would give us two free rings which he had as samples. He knows my sister is taken and has a boyfriend. But it was a kind gesture. Does it mean much?
