This stunning Art Deco Era ring is crafted and hallmarked of 835 silver indicating European origins. It is a stunning circa 1930s estate find that will adorn a size 7 finger. It's focal point is a faceted 10mm x 16mm faceted citrine colored crystal that is alive with color. I have not had this stone tested. It is accented on all sides with sparkling marcasites. The fancy work on the ends bring it to an overall measurement of 1'' x 3/9''. It is in beautiful condition with age appropriate wear.
