“Tis the season to put a ring on it — and thanks to lab-grown diamonds, those rings are bigger and cheaper than ever…

Lab diamonds continue to reshape the engagement ring market, with the prices of all diamonds dropping and more fingers dripping in multiple carats.

By the numbers: A natural 3-carat diamond could cost an average of 16 times the cost of a lab-grown version, according to data from independent diamond industry analyst Paul Zimnisky.

  • The Knot’s latest study found more than half of engaged couples (52%) had rings with lab-grown stones — a first for the annual survey.
  • And the stones went from an average of 1.5 carats in 2021, to 1.7 carats in 2024. According to Zimnisky, demand has particularly spiked for 2- to 3-carat natural diamonds and 3- to 5-carat lab diamonds.”
