If you are dead set on the two options you've mentioned with the goal being to match your current pieces, then another vote for Onyx.
But personally, I would get another variation - perhaps the new GMOP? Malachite? I love collections that are eclectic, and there are so many beautiful options. Good luck with whatever you decide.
