Vintage Estate 14k Aquamarine & Diamond Halo ring

This was passed down to me. I've worn it several times & it's very pretty on. The Aquamarine is a very light blue but it needs to be professionally cleaned & tested. I've priced accordingly. Here's what I've been told: Aquamarine surrounded with a halo of 10 diamonds. I don't know time period, only that I've had it a long time. To me, looks like they COULD be old mine cuts because of the distinct "hole" in the center, but until tested, no way to be certain. The prong setting seems rustic too.
