US researchers surveyed 3,000 American adults who had once been married for more than 13 years and found that men who spent between $2,000 and $4,000 (£1,244 and £2,488) on an engagement ring were 1.3 times more likely to get divorced than those who spent between $500 (£311) and $2,000 (£1,244).
However, the study also found that spending less than $500 on the ring also correlated with higher divorce rates.
The same also goes for wedding costs. Spending more than $20,000 (£12,444) on a wedding was linked to significantly higher divorce rates than those who spent between $5,000 and $10,000 (£3,111 and £6,222).
One listener on Premier's Woman to Woman programme thinks people seem to be missing the point. She said: "If you're in a financial position where you can spend that little bit more money or what's comfortable for you, then that's fine; but like I said, to just stress yourself out and worry about this and worry about that, I think we've lost sight of what marriage truly means."
The study also found that habits such as regularly attending religious services, having a baby, having a larger wedding (with more guests) and splurging on a honeymoon trip are all linked to a lower risk of divorce.
According to Brides magazine, its UK readers spent an average of £24,700 on their weddings, while the average price of an engagement ring was £2,451.
