    De Beers’ Gen Z diamond rebound: demand signals and price outlook for miners

    De Beers’ Gen Z diamond rebound: demand signals and price outlook for miners

    First reported on MINING.com

    30 Second Briefing

    Gen Z buyers are driving a rebound in US natural diamond demand, accounting for 23% of value while only 18% of the population, with average spend per purchase of $4,080 versus $2,250 for Baby Boomers and average stone sizes rising to 1.86 carats. De Beers’ data from 950 independent US jewellers show natural diamonds still command 85% of diamond jewellery sales value, despite lab-grown competition and total natural supply falling towards 90 million carats, the lowest since 1987. For Botswana, Angola, Namibia, South Africa and Lesotho, stabilising US demand and the Luanda Accord’s 1% rough-revenue marketing fund could support mine revenues and rough prices after several weak years.

    Technical Brief

    • De Beers’ US Diamond Acquisition Study surveyed 18,500 women, giving unusually granular demand segmentation data.
    • Natural diamonds were the top-ranked luxury gift for 11% of respondents, ahead of lab-grown at 8%.
    • Coloured gemstones and plain gold trailed far behind in stated desirability, at 5% and 4% respectively.
    • Average natural diamond jewellery ticket prices rose 25% year-on-year, from $3,242 to $4,063.
    • Bridal still dominates but only accounts for 45% of Gen Z natural diamond demand, indicating diversification of use-cases.
    • Non-bridal purchases now include promotions, career milestones, birthdays and self-reward, smoothing demand beyond engagement seasonality.
    • De Beers–Signet “Worth the Wait” campaign (launched October 2024) targets Zillennials with milestone-focused messaging.
    • Luanda Accord allocates 1% of rough diamond revenues to a Natural Diamond Council marketing fund.
    • Analyst Paul Zimnisky estimates 2026 natural diamond supply at ~90 million carats, the lowest since 1987.
    • Zimnisky reports early rough-price support, suggesting tightening supply–demand balance after four years of contraction.

    Our Take

    The rebound in natural diamond demand that De Beers is attributing to Gen Z comes as Anglo American has written De Beers down to $2.3 billion and is exploring an exit, so sustained US bridal and gifting demand will be central to any valuation case for potential buyers such as Botswana’s proposed sovereign-backed vehicle.

    With natural diamond supply estimated around 90 million carats versus 150 million carats historically, De Beers’ upstream technology push noted in our recent coverage suggests a parallel strategy: squeeze more value from a structurally tighter supply base through higher average prices and improved recovery rather than chasing volume growth.

    In our database of diamond-tagged mining pieces, only a handful link consumer behaviour metrics (like Gen Z’s 23% share of US natural diamond demand) directly to upstream strategy, which signals De Beers is unusually explicit in tying mine-side decisions and marketing spend (e.g. the 1% Luanda Accord contribution) to retail demographic data.

    EPC Groupe–Sabodala contract: blasting capacity and slope control insights for engineers

    EPC Groupe, through EPC Mineex Sénégal, has secured a five-year explosives supply and services contract with Endeavour’s Sabodala gold mine in Senegal, valued at about €10 million per year at full run rate. The deal covers bulk explosives and blasting support for one of West Africa’s largest open-pit gold operations, signalling a step-up in local emulsion manufacturing, on-bench services and blast design capability. For mine planners and geotechnical teams, the contract points to stable high-volume blasting capacity, supporting consistent fragmentation and slope performance over the medium term.

    Haultrax HX Coach in FMS: operational coaching and dispatch insights for mine teams

    Haultrax is integrating its on-site operational coaching directly into its Fleet Management System with the launch of HX Coach at IMARC 2026. The module is designed to embed real-time operator guidance and training logic into haulage fleet dispatch, moving beyond traditional FMS reporting towards in-cab behavioural feedback and decision support. For mine operators, this signals a shift from separate coaching programmes to a software-native approach that can systematically influence truck and shovel performance at scale.

    IsaMill at 30: fine grinding efficiency lessons for concentrator engineers

    Glencore Technology is marking 30 years of the IsaMill fine grinding mill, first developed by Mount Isa Mines and NETZSCH to tackle complex, ultra-fine regrind duties in base metal circuits. The horizontal, high-intensity stirred mill has since been deployed in more than 130 installations globally, often replacing ball mills in the sub-20 µm range to cut specific energy consumption and increase throughput. Recent IsaMill developments focus on larger M-series units, improved ceramic media wear performance and integration with modern flotation and coarse particle recovery flowsheets.
