Art Deco Red Coral Sterling Silver  Women's Ring Jewelry Vintage Sz 6.5

Please excuse the Red lint on the ring, i cleaned it off, i did not notice it until i listed pictures, i use a Macro lens so everything shows up in pictures that even our eyes can not see in person

Ring is a little dull from years but may just be the natural color and has not been buffed or any dyes added, some coral is very shiny but i think its because they buff and wax them ,,This is all Natural

Found at a Vintage Estate sale and i have not done anything to it

Tested Sterling Silver 

The stone is 11mm long and 6mm wide
