Will lab-grown diamonds capture more than 60% of the global diamond engagement ring market by volume in 2028?

The Diamond Shift: 60% Lab-Grown by 2028?

The price of lab-grown diamonds has plummeted, driving massive consumer adoption. This prediction asks if synthetic stones will account for over 60% of all diamond engagement rings sold globally (by volume) in 2028.

Price and Ethics

The 'Yes' vote is leading as the stigma around lab-grown stones fades, especially among Gen Z buyers who prioritize value and ethical sourcing. With lab diamonds trading at a fraction of the cost of mined equivalents (often 80-90% cheaper), the value proposition is undeniable for the mass market. While luxury brands push back with 'natural only' marketing, the volume trend in the mid-market strongly favors a synthetic takeover.
