Exciting! Emerald is my favorite CS. Showing you an additional design option by Kwiat, a more streamline and boundary pushing setting. It's glorious imo.
You seem to have a good jeweler to work with. Maybe ask him/her to call in a few Colombian ones since you’ve already looked at the Zambian material? You have an extended jewelry collection and are experienced to know what you do and don’t like, trust your gut.
Happy hunting 2022!
That bracelet is TDF and that emerald toi et moi is also stunning!
