14k GOLD Art Deco Aqua Blue Spinel Stacker Band Geometric Shoulder Emerald Cut?

Description

I am selling an assortment of vintage to antique jewelry and rings which I have hunted for and gathered from around the world.  Please see my other offerings and thanks for stopping by!
ABOUT:
Elegant Art Deco 14k solid gold ring, with geometric shoulders and a rectangular (perhaps similar to emerald or radiant cut?) pale blue spinel.  Dainty band with beautiful detailing on the ring face when viewing the gold from the side, would make an excellent stacker.  I am not sure if the spinel is natural or lab created as I am not trained as a gemologist to decipher but it did test accurately as spinel on my gem tester.  The stone is such a beautiful color, it really glows.
This is a vintage to antique piece that I acquired in Europe.  As such it is marked with their numerical gold marking system, in this case 585 for 14k gold.
SIZE & MEASUREMENTS:
Currently a size 7. The stone is about 11.5mm by 8.5mm so a very nice size stone.
IMPORTANT CONDITION NOTES:
All my pieces are preowned and in estate condition.  The stone has some tiny fleabites along with some scratches on the facet edges, seen mostly under magnification, not really visible to the naked eye unless you really study it up close in a bright reflection. Some surface wear and scratches to the gold from wear over the years but the band and gold is in nice shape.  Due to age -  Please note this is not a mint condition item.
Thanks so much for looking at my items!
