Investing in natural diamonds

The natural diamond, a rare and valuable asset, draws its worth from the unique dynamics of its market. Understanding these specificities — and the mechanisms that shape its global trade — is key to investing with confidence in this exceptional stone.

The Global Market:
Key Players and Dynamics

Diamonds follow a structured path: extraction, cutting, certification, and distribution. Rough stones, extracted in regions such as southern Africa, Russia, or Canada, are first resold via auctions by major producers like De Beers or Alrosa.

They are then cut by experts, often in India, Belgium, or Israel, before being certified by independent laboratories. The diamonds subsequently circulate on specialized exchanges such as Antwerp or Dubai.

The diamond trade is strictly regulated by international laws and the Kimberley Process, which combats conflict diamonds. Thanks to global databases and advanced traceability tools, the provenance of stones is assured, enhancing transparency throughout the market.

THE RAPAPORT:
the benchmark price index

The Rapaport Diamond Report, created in the 1970s by Martin Rapaport, is now the world’s leading pricing authority for polished diamonds. Published weekly, this chart provides indicative prices in US dollars based on the 4Cs (carat, color, clarity, and cut).

It serves as a basis for international pricing, functioning like an official price list. Although final prices may vary depending on rarity or negotiations, the Rapaport remains a tool of transparency, stability, and trust—especially for investors.

It is the industry professionals’ benchmark: a reliable reference for comparing, estimating, and investing accurately.

Diamonds: a valuable asset

  • Sustainability and natural rarity

    Formed over billions of years, natural diamonds are a finite resource whose intrinsic rarity and durability make them a long-lasting and highly sought-after asset.

  • Ease of transport and discretion

    Compact and discreet, the diamond packs a great deal of value into a very small volume, making it an easily transportable and storable asset.

  • Safe haven against inflation and crises

    Historically, diamonds have demonstrated long-term stability, positioning them as a tangible safe haven amid economic uncertainties.

  • Diversification of an asset portfolio

    With little correlation to traditional financial markets, diamonds offer an intelligent diversification option within a wealth portfolio.

Invest with confidence

Investing in diamonds requires a deep understanding of their specific characteristics. While the 4Cs remain essential benchmarks, other factors also influence a stone’s value: the rarity of particular features, market trends, and the quality of the certificate.

Each diamond must be evaluated in its unique context, making professional guidance crucial. Investing isn’t reserved for connoisseurs alone— with the right advice, it becomes an accessible, tangible, and meaningful opportunity.
