Antique Vintage Art Deco Silver,  Green Agate + Marcasite Ring
Egyptian revival style, lovely decorative item.
I am afraid I do not have a ring size, other than to say it is quite small.  Measuring approx 15mm diameter.

I believe this was made in the UK, but not 100% sure.

Unfortunately the metal is not marked, but I believe it is silver.

This dates from the 1920's, or early 30's.

Good condition.  Supplied in a box but not the original
