But should the singer return it? Read these opinions and take part in our poll below!
YES says account manager Paul Howe, 33:
An engagement ring is only given to someone when you want to marry them. Unlike a watch, or a necklace, or a pair of Louboutins that can be given for any occasion, an engagement ring has one – and only one – purpose. Therefore, if the marriage doesn't happen, I really believe that the ring should be returned as part of the same process.
My former fiancée didn't return the engagement ring that I gave her, which I wasn't happy about. She said it was symbolic but, to me, all it symbolised was a time when we wanted to get married, and we no longer did. It would be really odd if she wore it after we split. Even if she had the diamonds taken out and put into a pendant, it would still have been a bit off.
It's hardly an heirloom to pass down the generations. And if she tried selling it, it wouldn't have been worth a great deal of money (even though it cost me a lot at the time).
Therefore, I honestly think she, and a lot of women who keep hold of their engagement rings, do so out of spite. She doesn't want me to get any money from it or pass it on, although let's be honest, only a jerk would recycle an engagement ring.
It's sad because we didn't have a messy break-up. We made a mutual decision to end things and everything we'd bought together, or spent on our wedding, we split between us. Everything, except the engagement ring.
Two years ago, I had a relationship with a man who was Turkish (yes, I know, major cliché but you can't help who you fall in love with and all that). After a year and a half of me flying over there whenever I could get out of uni, he proposed and I accepted, with the intention of him moving to England.
Unfortunately, the UK visa system isn't as easy as newspapers make out and he was only able to visit England a couple of times because we weren't married. As much as I loved having a holiday every two months, the distance became too much and we split. The ring's tucked away in my jewellery box – I never even considered giving it back to him.
It'd be wrong to keep the ring to sell it, so there was no way I was going to give it back so he could – or worse, use it to propose to someone else! I'm sure some people want to erase all trace of their ex, but we still talk and didn't end badly, so the ring's just a memento of our time together.
In Turkey, the man also wears an engagement ring so they were not only a symbol of commitment, but also a gift to one another. I didn't return other gifts he gave me, so why would I return the ring? Not to mention the fact the postage cost to send it to Turkey safely would be ridiculous!
