Truly beautiful Art Deco marked “sterling” and marcasite ring.  The ring has original, rich patina that I believe enhances the appearance of the ring.  As seen under a glass, there is one missing marcasite at the top and a couple are not perfect, but for it’s age, the ring is in nice shape.  There is an unresearched maker’s mark that looks like a J with an arrow. 

The crown is 1 1/8” high.  The ring is just a hair under size 7 on my mandrel.  Weight is 6.15 grams.  Good condition with nice appearance
