I am lost. Is it because of the translation? What's with that ring?

Look at the princess hand from previous chapter. She took duchess engagement ring. And well as we all know, duke is really disgusted with this bitch, so he just rather let this ring burn (even tho it's family heirloom) than let his wife wear it again

Thank you for the info. I'll wait for the official translation then to better understand the conversation between theo and the king
