India, Belgium, and the United Arab Emirates are the leading exporters of diamonds (CAS 7782-40-3), collectively accounting for over 60% of global diamond exports by value; the United States, China, and Hong Kong SAR are the largest importers, driven by jewelry manufacturing and retail demand. Diamond prices have shown moderate upward pressure since 2023, coinciding with tightening supply from major mining nations and sustained demand in premium consumer markets.
Diamond is a naturally occurring, crystalline allotrope of carbon, appearing as a transparent to translucent, extremely hard solid with no odor or volatility. It is classified as an elemental substance (pure carbon) in its diamond cubic crystal structure and has no defined boiling point; it sublimes above ~4,000 °C under inert conditions. Diamond is not used as a chemical intermediate but serves primarily in industrial applications requiring exceptional thermal conductivity, hardness, and optical transparency. Key uses include cutting, grinding, and drilling tools; heat sinks in high-power electronics; optical windows for lasers and sensors; and wear-resistant coatings. It is employed across sectors including precision machining, semiconductor manufacturing, defense optics, and high-performance instrumentation.
