Unmarked, but all the indications of a West German filigree design.
A stunning Vintage Turquoise Ring, in a gold tone metal mount.   An ornate scroll setting.  Twin shoulders have been set with small blue crystal stones.  The shoulder settings are Fleur de Lys, the small stones being the centre of 2 small flowers each with the Fleur De Lys scrolls.  A nice, secure claw setting, with collar.  The single Turquoise stone is rectangular, measuring 2cm x 1.5cm, domed with a flat back.  Adjustable.
No maker's mark.
Found in a drawer of an elderly relative when sorting out.  Art Deco in style.
Quite a striking ring, weighing 7g.
My home is pet & smoke free.
I will post Evri.
Thank you for looking.
