The diamond industry links mining, trading, cutting, certification, and retail from Africa and Asia to Europe and the United States. In 2023, global jewelry value dominated the picture, while cutting and polishing remained a labor-heavy process centered in India. Certification coverage continued to expand and import rules evolved, influencing sourcing, labeling, and due-diligence requirements. Production and export dependence also vary widely by country, from Botswana to Angola and beyond.
