Thoughts on this 3-stone with emerald center?

[viggy_luvs_bling]

Howdy! I considered posting on the Colored Stones forum but since this Instagram reseller is popular on the antique forum here… thoughts on this 3-stone, in particular the emerald center? Is it too too “windowed” since I can see the gold ring band behind the stone? I love the color and proportion but not experienced with emeralds. And usually items sell out within minutes of her posting so a bit hesitant since this one is still around. Any thoughts or comments would be appreciated!
