In 2025, the diamond market witnessed a notable shift in consumer preferences and sales dynamics, with GN Diamond reporting a near-even split in the unit sales of lab-grown and natural diamonds. Lab-grown varieties constituted 55% of total diamond sales, indicating their growing accessibility and appeal, particularly as an affordable option for finished jewelry and engagement rings. This expansion suggests that lab-grown diamonds are successfully attracting consumers who might otherwise have invested in other luxury goods, thereby contributing positively to the overall growth of the jewelry industry.
Despite the high volume of lab-grown diamond sales, natural diamonds unequivocally maintained their dominant position in terms of financial contribution. Natural diamonds were responsible for a substantial 76% of revenue and an even more impressive 82% of gross profit. This underscores their enduring value, especially for significant purchases, investment-oriented transactions, and classic bridal pieces. Retailers, engaging with over 3500 counterparts weekly, reported a robust conclusion to 2025, marked by a significant upswing in natural diamond sales during the holiday season compared to the previous year.
Looking ahead to 2026, market forecasts project stability or even modest increases in the prices of natural diamonds, particularly for rare, high-clarity stones. This trend is attributed to a limited supply and sustained demand within the luxury sector. GN Diamond has already observed an upward trajectory in natural diamond sales across all sizes over the past six months, with round and oval cuts remaining highly sought-after. Additionally, fancy shapes such as marquise, emerald, elongated radiant, and cushion cuts are experiencing strong demand, highlighting a diverse and active market for natural gemstones.
The evolving diamond market presents both opportunities and challenges, with lab-grown options expanding consumer access while natural diamonds retain their premium value and appeal. This dynamic landscape encourages innovation and strategic positioning for businesses within the industry, fostering a vibrant and competitive environment where both types of diamonds cater to distinct market segments. Embracing diverse offerings and understanding consumer motivations will be key to continued success and growth in the global jewelry sector.
