French PINK Sapphire 18k GOLD Floral Halo Ring Antique Art Nouveau Belle Epoque

Description

I am selling an assortment of vintage to antique jewelry and rings which I have hunted for and gathered from around the world.  Some examples seen in the last photo - thanks for stopping by!
ABOUT:
Beautiful Art Nouveau to Art Deco antique ring with a pink gemstone with a floral design reticulated and scalloped halo in white gold.  It has the beautiful, I'm not sure what it is called - reticulated lattice like work to the gallery which is seen in antique rings of this period. Would be beautiful in a ring stack.  Dainty and lovely antique piece with eye catching color.
This is an antique piece from the Belle Epoque period.  I purchased it from a little antique shop in Wisconsin and the dealer told me it was French.  No hallmarks but it tests at 18k plus.
The gemstone is a lovely shade of pink and tested high for hardness on my Presidium gem tester in the Ruby / Sapphire range.  I am not a certified gemologist so I am not exactly sure what the stone is, only that it tested in that range so it is not glass/ paste.  It is a gemstone, although I am also not sure if it is natural or synthetic.
MEASUREMENTS:
Ring is currently a size 6 3/4. The pink gemstone measures about 5mm in diameter, very vibrant in color and reflects the light. The ring face is about 10mm wide.
IMPORTANT CONDITION NOTES:
Please note that all my pieces are in estate condition.  Quite a bit of surface wear and scuffs to the facet edges of the stone when I look at it under strong magnification.  Not super visible to the naked eye, but if you look at it up close in direct bright light you might notice it.  There is a slight curve to the gallery where it has bent slightly but this is not visible when wearing the ring.  Only when you look at it from the underside.  Some surface wear, to the gold.  Still a fantastic and eye catching piece.
But of course due to age - Please note due to age, this piece is not in mint condition.  I always recommend gentle wear for these antique pieces.
I would be delighted if you'd follow me.  Thanks for stopping by!
