This set of 2 key-style rings is originally from the 'Gladys Joyce Bowden' collection. The 'I ♥ U' set was made especially for the set of season 2 of TV show  and was worn by beloved serial killer Villanelle (played by Jodie Comer)

The set features 2 rings, that when worn together say "I ♥ U".
The rings are designed as a vintage-style key, with the letters representing the key's teeth.
On the back of the shanks are engraved the words "mine" and "yours", so you can keep one ring and gift the other, as a special sentimental message, known only to the wearers.

The sterling silver rings are partially gold plated, to highlight the design.
