In the last year, we've seen antique gold (or gold plated) envelopes on necklaces, charms and even earrings. This is the first time I've seen it on a ring though. And it's a bit of a knuckle duster.
Topshop are the creators behind this particular ring, which features a tiny postcard attached with "I Love You" scribbled across it. It's actually gold-look rather than anything containing carats, but at only £6 you can't really complain.
Have you ever sent a love letter?
