But modern jewellery can be incredibly expensive - and do you get your money's worth? Will that diamond continue to be worth what you paid for it?

Another option is to look to an auction, where you can pick up a stunning piece of modern jewellery that you know will hold its value, because it has been valued by an independent jewellery expert.

For example, there is a stunning single stone diamond pendant coming up for sale at UK auctioneers Fellows & Sons soon.

It is the highlight of its antique and modern jewellery auction, which can be viewed online at .
