The brand has lowered prices to as low as $500 per carat, down from the previous $800 per carat.

This decision follows extensive research and testing in the lab-grown diamond jewellery sector, reflecting a shift in pricing dynamics. Lightbox now offers three distinct price points: $500 per carat for IJ colour stones, $600 per carat for GH colour stones, and $900 per carat for the highest quality stones of DEF colour, previously priced at $1,500 per carat. All stones come with a guaranteed minimum 'very good' cut and VS clarity, while DEF stones feature an 'excellent' cut.

Sandrine Conseiller, CEO of De Beers Brands, stated, "As wholesale prices for lab-grown diamonds in the jewellery sector continue to decline, we are pleased to pass on these savings to our customers. These adjusted prices ensure Lightbox remains competitive in a rapidly evolving market while maintaining our commitment to high-quality lab-grown diamonds produced with 100% renewable energy. Lightbox has always adhered to linear pricing, reflecting the production costs transparently and distinguishing lab-grown diamonds for what they are, and what they are not."

Conseiller continued, "The widening price gap between natural and lab-grown diamonds underscores their fundamental differences in the eyes of consumers. For instance, a two-carat highest quality lab-grown diamond from Lightbox now retails for approximately 10% of the price of a comparable natural diamond of the same size and quality. This price trend reaffirms our belief that lab-grown stones' primary appeal in the jewellery sector lies in fashion jewellery, where lower price points allow for playful and colourful innovations, such as the blue and pink Lightbox stones. Jewelry consumers must recognize that lab-grown diamonds constitute a distinct product category, lacking the enduring value of natural diamonds."
