Are natural diamonds rare?

Natural diamonds are considered rare due to their formation process, which takes place over millions or billions of years in limited zones of the Earth's mantle under extreme temperatures and pressures. The recovery of natural diamonds has been declining, with global production peaking in 2005. Currently, there are only 30 significant natural diamond mines in production, and the success rate of diamond exploration is estimated to be less than 1%. The supply of natural diamonds is finite and their supply is decreasing. This means that there is a limit to how many natural diamonds can be mined, and that they will become more valuable in the future.

The closure of mines that have reached the end of their economic lives, such as Argyle in Australia and Victor Mine in Canada, further contributes to the changing landscape of natural diamond mining. Exploration for new diamond sources requires significant financial investment, and determining the economic viability of projects is a complex process. The gradual decline in rough diamonds recovered and traded under the Kimberley Process Certification Scheme also reflects the diminishing supply of rough diamonds. Overall, the rarity of natural diamonds is attributed to their geological formation and the challenges in discovering and extracting them.

How are natural diamonds ethically sourced?

The natural diamond industry is committed to ensuring ethical sourcing practices. The industry is highly regulated through initiatives like the Kimberley Process, mandated by the United Nations and the World Trade Organization, to ensure that rough diamonds are conflict-free. The process involves audits of major industry players and has strict checks and balances to enforce ethical standards.

Ethical sourcing in the natural diamond industry means obtaining products and services in an ethical manner, including upholding labor rights, providing decent working conditions, and avoiding child labor. It also emphasizes strong business ethics and respect for local communities. The industry has been working to address legacy issues related to mining practices and conflict diamonds and is held to high trading standards, as the majority of diamonds are extracted and marketed by large mining companies that are accountable to shareholders and stakeholders.

Transparency and traceability of diamonds in the supply chain have become important factors, driven by pressure for mine-to-market accountability. The Kimberley Process Certification Scheme (KPCS) is a foundational block in achieving ethical sourcing, requiring transparency, exchange of statistical data, and export and import controls. Over 80 countries participate in the process, and conflict diamonds now account for less than 1% of recorded rough diamond trade, a significant improvement from the past.

The industry has established its own standards, codes of conduct, and guidelines to ensure ethical practices. One example is the World Diamond Council System of Warranties, which requires professional buyers and sellers to include a warranty statement on invoices and memos, confirming the diamond's conflict-free origin and adherence to responsible business practices. The System of Warranties covers human and labor rights, anti-money laundering, and anti-corruption measures. Retailers also abide by the System of Warranties, and major jewelers like De Beers, Chow Tai Fook, and Tiffany & Co. reference it in their supplier codes of conduct.

Is the industry stockpiling diamonds to drive-up prices?

The idea that the diamond industry is stockpiling diamonds to drive up prices is not supported by the available data. Inventories of natural diamond producers fluctuate over time due to various factors such as the size, color, and quality of the stones recovered each month, seasonal demand fluctuations, and external events like the global coronavirus pandemic.

Comparisons of production and sales data for diamond companies show that there is no evidence of deliberate stockpiling to systematically increase prices. In fact, upstream inventories at diamond mine sites and sorting offices fell by 40% in 2021, bringing them close to minimal levels. The diamond industry has been transparent in disclosing production and inventory management information, and the international rough diamond trade is regulated and recorded through the Kimberley Process Certification Scheme.
