16,000 carat Marange Diamonds17 Nov 2025 21:16
Valuing 16,000 carats of high-quality, cut and polished diamonds from the Marange fields (Zimbabwe) requires breaking down several key factors, because Marange diamonds have unique market characteristics.
### Key Characteristics of Marange Diamonds
- Mostly small-size stones (average rough ~0.5–2 carats, so cut stones typically 0.2–1 ct after polishing).
- Predominantly near-gem or gem quality, but often with brown, gray, or yellowish tint.
- High clarity is common (VS–SI), but strong color (D–H) is rare. Most high-quality Marange goods fall in I–M color, sometimes better.
- Heavy historical discount (2010–2020) because of sanctions, KP issues, and massive supply flooding the market.
- Since ~2022, sanctions lifted and supply reduced → prices have risen significantly, especially for well-cut, clean, white goods.
### Current Market Reality (November 2025)
Clean, well-cut Marange-origin goods now trade much closer to “normal” (non-sanctioned) diamond prices, but still at a discount to top-tier sources (Canada, Russia, Botswana) for comparable quality.
Typical price ranges for high-quality cut Marange diamonds (2024–2025 wholesale/rap prices adjusted):
| Size (carat) | Color / Clarity | Approx. price per carat (USD) | Notes |
|-------------------|------------------------|-------------------------------|------------------------------------|

| 0.30–0.49 | F–I / VS–SI | $1,800–3,800 | Very good white smalls |
| 0.50–0.89 | E–H / VS–SI | $3,500–6,500 | Premium small singles |
| 0.90–1.99 | D–G / VVS–VS | $6,000–12,000+ | Rare in Marange; top goods |
| 2.00–3.00 | E–H / VS | $8,000–15,000 | Extremely rare from Marange |
