Diamond prices fell 26% in two years — here is what De Beers and Botswana's marketing bet means for a jeweler in Chisinau

When the world's most iconic luxury category loses its pricing power, the ripple reaches every market that carries it.

Natural diamond prices have fallen 26% over the past two years. Lab-grown diamonds have dropped 74% in price since 2020. Against that backdrop, De Beers and the Government of Botswana announced a co-funded category marketing initiative designed to restore the perceived value of mined diamonds — with financial responsibility split according to each party's share of Debswana's diamond supply. It is a significant bet on narrative over fundamentals.

The numbers behind the announcement are stark. In 2024, De Beers' rough diamond sales fell for the second time in the year, recording a provisional $315m — down from $383m in the previous cycle and a steep drop from $456m at the same point in 2023. The company attributed part of the decline to a quieter summer period, but industry analysts pointed to something more structural: a market where demand has not recovered and where lab-grown alternatives have permanently repositioned the category's price ceiling.

The deeper story is not about marketing budgets. It is about what happens when a product that derived its value almost entirely from scarcity and symbolism collides with a scalable, cheaper substitute. De Beers built one of history's most durable brand narratives around natural diamonds. Now it is being asked to rebuild that narrative in a market where a lab-grown stone is visually and chemically identical to a mined one — and costs a fraction of the price. That is not a communications problem. It is a value-proposition problem that marketing can slow but not reverse.

For a jewelry retailer or goldsmith operating in Moldova, this global price collapse creates a specific operational problem: inventory valuation. Natural diamond pieces purchased at 2022 or 2023 wholesale prices are now sitting on shelves against a market where replacement cost is materially lower. A retailer who bought inventory at the peak is not just facing a margin squeeze — they are facing a structural mismatch between their cost base and what the current wholesale market would imply as a fair price for that product.

The competitive pressure runs in both directions. On one side, internationally sourced lab-grown diamonds are entering the European market at price points that make natural stone pieces look expensive by comparison. Moldova's EU candidate status means that import channels from EU-based distributors are becoming more accessible, which accelerates the arrival of these products into the local supply chain. A goldsmith in Chisinau who sources exclusively through traditional natural diamond wholesalers will face growing price competition from pieces carrying stones that are chemically identical but priced off a completely different cost curve.

On the supply side, the De Beers and Botswana marketing initiative is explicitly a category play — meaning its benefits, if any materialize, will accrue to the entire natural diamond segment, not to any single retailer. A small jewelry operation in Moldova will not be a direct beneficiary of that campaign spend. What it can do is position its natural diamond inventory around the ethical and provenance arguments that the campaign is designed to amplify — certified origin, traceability, the social and economic weight of the mining economies behind the stone. That is a pricing-support argument, not a volume argument, and it requires a different kind of sales infrastructure than most small jewelers currently maintain.

Anyone carrying diamond inventory right now should be asking themselves three questions. First: at what wholesale price was my current stock acquired, and does my current retail pricing still reflect a defensible margin given where natural diamond replacement costs sit today? Second: does my supplier base give me access to lab-grown product if segment demand continues to shift, or am I structurally locked into one side of a bifurcating market? Third: is my current merchandising built around the symbolic and provenance story that the De Beers campaign is trying to reinforce, or is it built around a price-to-size value equation that lab-grown stones will win on every time?

Most jewelry operators in this position default to holding inventory and waiting for prices to stabilize. A more deliberate response is to audit the cost basis of existing stock now and decide, before the next buying cycle, which part of the portfolio is positioned to hold value and which part needs to be repriced or liquidated.
