The lab-grown diamond sector has reached a historic milestone, now accounting for more than half of all engagement ring purchases—a first for the industry. This represents a 6% year-over-year increase and a striking 40% surge since 2019, driven primarily by millennial and Gen Z consumers who are redefining the bridal jewelry landscape. Data reveals a profound shift in buying behavior: lab-grown engagement rings now boast an average center stone of 2.0 carats, compared to 1.6 carats for natural diamonds, while the overall average carat weight has risen from 1.5 carats in 2021 to 1.7 carats in 2024—clear evidence that consumers are prioritizing larger, higher-quality stones without overspending.
