How much money do you spend on engagement rings?
Past traditions dictate that three month's salary should be spent on an engagement ring, however, these days there's no one-size-fits-all approach. Everyone has a different idea of budget and with so many designer and high-street jewellers offering a wide range of stunning styles, price doesn't have to be a major cause for concern.
How many carats is appropriate for an engagement ring?
According to Diamond Heaven, in the UK the average carat size for a diamond engagement ring is between 0.5-1 carats, although some suggest it's 0.6 carats. Of course, there's no pressure to abide by a certain carat size as other factors such as budget and style can impact your final choice.
