Lovely french ring circa 1810-20, decorated with black enamel, with accents of white enamel, in a foliate pattern, the central panel set with a rose cut diamond set in a silver pinched collet setting.
The reverse of the ring has a tiny hinged locket door, no doubt it held hair at one point.
 
size 7.2, the ring has been sized but the hallmarks have been preserved, a shell and a dove.
 
18 carat gold 
weight - 3.8g
condition - the enamel is in good order save slight wear at the back edges.
