cartier love ring

[Brielle Gonzales]

Please let me know if this is the wrong forum to post on, but I am really hoping for some help. I want to purchase a second hand cartier love ring. However, I am unsure of whether it is authentic. Also, do cartier love rings have 'love' engraved onto the side of the rings? i have attached a picture of the ring for reference. Apologies for the blurriness of the photos, they were taken by the seller. The ring has the cartier logo on top and the ring information spans 3 lines, which I have never really seen. Thanks!
