Unusual late c18th navette shaped mourning  ring with a forget-me-not blue enamel urn set to a cobalt blue glass ground.c.1780.
There is also a border in the same pale blue enamel,and the plinth to the urn has a white enamel rectangle (for initials)which has been left unmarked.
18 carat gold, the shank is a later replacement.
As the ring has no inscription to the reverse it is likely it was a jewellers sample or was sold undedicated.
Size 7.
