Natural diamond prices have increased 5-8% year-on-year, driven by production cuts from major miners like De Beers to manage inventory. While high-end solitaires are attracting investor interest, smaller stones face heavy price pressure from lab-grown alternatives. The market is also benefiting as cooling gold prices encourage consumers to return to diamond jewelry.
What Happened
Natural diamond prices have seen a recovery, rising 5-8% over the past year. This comes after several years of price stagnation. The primary driver is a strategic decision by major global miners, including De Beers, to reduce the supply of rough diamonds. By limiting the amount of diamonds entering the market, producers are trying to balance inventory levels and prevent further price erosion. In India, a one-carat natural diamond solitaire is now priced around ₹1.85 lakh. This price uptick is part of a broader trend where industry leaders and collectors are increasingly positioning high-end natural solitaires as a store of value.
The Lab-Grown Diamond Challenge
While the headline numbers for rare, high-end solitaires are positive, it is important for investors to note the split in the market. The industry faces a significant challenge from lab-grown diamonds (LGDs). These diamonds are chemically identical to natural ones but are significantly cheaper to produce. This has created intense pricing pressure on smaller, commercial-grade natural diamonds. While rare, large solitaires (typically used for investment or high-end jewelry) are insulated by their scarcity, the mass-market segment of small diamonds is struggling to compete with the lower price points of synthetic versions. For investors in diamond-processing companies, this shift remains a critical area to monitor.
The Gold Substitution Effect
Diamond demand is often linked to the broader jewelry market, particularly gold. When gold prices reach record highs, consumers often pull back. Recently, gold prices in the Mumbai spot market have seen a correction, trading lower than their peak levels of nearly ₹1.8 lakh per 10 grams seen earlier this year. This pullback has helped shift some consumer spending back toward diamond jewelry. As natural diamonds become a more attractive alternative to expensive gold, jewelry retailers may see a boost in demand.
India’s Role In The Global Chain
India acts as the world's primary hub for diamond processing, handling over 90% of global rough diamond polishing. This makes the Indian gem and jewelry sector highly sensitive to global demand trends. India has become the second-largest and fastest-growing market for diamond jewelry, now accounting for 12% of global demand value, up from 8% in 2021. For listed players like Titan (Tanishq), Kalyan Jewellers, and Senco Gold, the trend toward branded solitaire jewelry offers a different dynamic than it does for pure-play diamond polishers, who are more exposed to the raw material price fluctuations.
What Investors Should Monitor
Investors should keep an eye on three key factors. First, the price gap between natural diamonds and lab-grown diamonds; if LGD prices continue to fall, it may keep pressure on small natural diamond prices. Second, the inventory levels of major miners like De Beers; sustained supply cuts are necessary to maintain this price rally. Third, consumer demand in India; as the market shifts from unorganized to branded diamond jewelry, companies that can successfully market the 'investment' and 'rarity' value of natural solitaires may differentiate themselves from the commodity-grade stone market.
