The explanation is as follows: the ring represents a sense of sustenance, and jade itself is a symbol of purity and nobility. This may happen in your dream because you are making a difficult choice recently. You need to make a choice between two very similar people or things, but you actually have an answer in your heart but are unwilling to give up the other one, because there seems to be no reason to refuse, but I suggest you follow your heart. Sometimes it doesn't have to be a reason. The reason is that your heart tells you so. Don't go against your own ideas. It's easy to lose both sides and get nothing.
I hope it helps you!
