Bigger isn't always better-- at least when it comes to the relationship between engagement ring size, and the length of a marriage.
Emory University surveyed 3,000 adults nationwide who had been married at some point in their lives. The results show couples who spent the most money on the ring and the ceremony were more likely to end up divorced.
Rings costing between $2,000 and $4,000 were 1.3 times more likely to get divorced than men who spent less. However, rings costing less than $500 were more likely to get divorced as well.
The average wedding ring costs $3,000.
Researchers also found couples that had more guests, and went on a honeymoon stayed married longer.
