Isn't this special. It's a rare vintage solid 9ct yellow gold enamelled playing card charm, the ‘Ace of Hearts’. 
 
A very lucky find, this one, fully hallmarked for Birmingham 1955 and in very excellent condition with no visible chips to the enamel & only a very slight wear to the markings, commensurate with age.
We rarely see enamelled charms of this age in such great condition, truly a very rare piece that would make the perfect gift for the one you love.
 
Please note the measurements, it is quite small, which makes the clarity of the enamel even more remarkable.
Comes with a jump ring ready to attach to your bracelet.
