Expect to pay more than $167,000 for a 10-carat diamond engagement ring. This price is based on the lower end of the scale according to a diamond’s quality and grade. Stones with a higher grade command a higher price per carat.
You can save money on a 10-carat ring by choosing a lab-grown diamond. Although chemically and visually identical to mined diamonds, the price of these stones does not increase exponentially with weight.
