“No longer an alternative, but mainstream”: Lab-grown diamonds reshape the wedding market

Lab-grown diamonds are no longer being treated as a fallback in the wedding jewelry market. They are becoming a mainstream choice for consumers seeking the look and properties of natural diamonds without the same price burden.

The stones have physical and optical properties similar to natural diamonds, while their lower cost is driving consumer interest. Alexis Nasard, Swarovski’s chief executive, told the Financial Times that more than 60% of the U.S. engagement-ring market has already chosen lab-grown diamonds. He expects that share to rise to 80% within the next two years.

The global shift is accelerating in South Korea as well. Honest Seoul, a specialist lab-grown diamond brand, said sales of proposal rings rose 112% from March to August compared with the same period a year earlier.

Consumer preferences are also broadening. Alongside classic round cuts, demand is increasing for oval, pear and marquise cuts, as well as for larger carat sizes. Pavé designs, which closely set stones across the band, are also drawing attention. Engraving services for anniversaries and initials are being offered alongside the expanding range of designs.
