Lab-Grown Diamonds Recast Luxury Wedding Jewellery

Lab-grown diamonds are moving from alternative choice to wedding mainstream, forcing the jewellery industry to reconsider what luxury means at the bridal counter. In the US, 61 per cent of engagement rings bought in 2025 featured lab-grown centre stones, according to The Knot, up 239 per cent since 2020.

The appeal is reshaping expectations. Lab-grown rings averaged about $4,300 with a two-carat centre stone, compared with $7,000 and 1.6 carats for natural diamonds. Couples are effectively buying greater visual impact for less, weakening the old equation between rarity, size and prestige that underpinned traditional diamond selling.

For luxury jewellers, the shift is creating a sharper divide. Natural diamonds are being pushed further towards provenance, scarcity and emotional permanence, while lab-grown stones increasingly compete through design, scale and accessibility. Rapaport reported in September that natural diamond prices showed signs of recovery in August, although synthetics continue to influence demand across the trade.

The brands that helped establish lab-grown jewellery are adjusting too. Dorsey is broadening beyond diamonds into sapphires, moissanite and coloured stones, while preparing for physical retail in New York. Its positioning now places greater emphasis on design and recognition than on lab-grown provenance itself. Pandora, meanwhile, has introduced carbon-footprint disclosure across its lab-grown diamond collection, adding transparency to an increasingly competitive category.

That evolution marks an important turn. Lab-grown diamonds have become common enough that technology alone can no longer confer distinction. Luxury is returning to harder-to-copy qualities, craftsmanship, identity, service and story. Natural diamond houses, meanwhile, must articulate why rarity still commands a premium. Bridal jewellery remains deeply symbolic, but the industry can no longer assume that expense and prestige mean the same thing.
