If you're on a budget, a vintage engagement ring is likely to save you money (after all, romance is not a good reason to get into debt). Of course, you can still spend £20,000 on an Art Deco sapphire the size of a small island if that's what you want, but in the world of antique and vintage jewels, it's always possible to get a good deal, and you might even get to do a bit of haggling.
Top tip: Most vintage and antique rings won't be perfect, so consider their imperfections part of their charm. If there really is something that will need fixing, such as a missing stone, you can use this to get a better deal.
