They say a diamond is forever, but can it lead to divorce?

New research from Emory University suggests the bigger the diamond, the shorter the marriage.

But it’s not just about the big bling.

The study also suggests the more expensive the wedding, the higher the divorce rate.

Researchers surveyed 3,000 adults who have been married at some point. Here’s what the study found:

Men who spent between $2,000 and $4,000 on a ring were more likely to end up divorced than men who spent less than $2,000.

The same is true for the women receiving the rings. The more expensive — the more likely women reported being divorce.

As for those big fat weddings? Women whose big day cost $20,000 or more are 3.5 times more likely to divorce than women who spent between $5,000 and $10,000.

For men who want to use this to get out of buying a more expensive ring should know there’s one catch: potential grooms who spent less than $500 on a ring also experienced high rates of divorce.
