The global nano‑diamond powder market reached ~USD 1.2–1.25 billion in 2023, forecast to grow to ~USD 2.5–2.7 billion by 2032/2033 at ~8–8.5% CAGR. A specialized subset—nano‑diamond used for semiconductor wafer grinding and CMP—has rapid growth; U.S. slurry market alone was USD 50 million in 2024, predicted to reach USD 90 million by 2033 (~8.2% CAGR). Nano‑diamond powder pricing is strong due to supply constraints and technical complexity. Global diamond powder prices increase 6–7% CAGR projected to reach USD 1.3 billion by 2031.
