This is an unusual vintage ring featuring a hand painted portrait mounted in 800 silver (a lower grade of silver than sterling). It represents Flora from Botticelli's painting Primavera (Spring). I have seen a number of pin/pendants with these hand painted portraits but this is the first ring I have encountered. These were purchased as souvenirs. It is marked 800 on the back.
The ring is a size 7 1/2 and could be resized up or down a bit by a jeweler. It is very large for a ring. The face measures 1 1/2 inches by 1 1/4 inches. It is in very nice condition.
