Emerald
Colombia grows the finest emeralds; Zambia grows the most. What emerald is, where it comes from, and why origin is everything.
Last updated: October 2026
Emerald is green beryl, coloured by chromium or vanadium, famed for its inclusions — the 'jardin' that gemologists read like a fingerprint. Colombia grows the finest stones at Muzo; Zambia grows the most at Kagem. In emeralds, origin is everything.
| # | Country | Share |
|---|---|---|
| 1 | Zambia | ~35% |
| 2 | Colombia | ~25% |
| 3 | Brazil | ~15% |
| 4 | Ethiopia | ~8% |
| 5 | Afghanistan | ~5% |
Gemstone production shares by volume, approximate (GIA; USGS Mineral Commodity Summaries 2025 — Gemstones). Value shares differ sharply from volume shares.
Emerald is the green variety of beryl, a beryllium aluminum silicate coloured by chromium or vanadium. It scores 7.5 to 8 on the Mohs scale but is brittle and famously included — nearly all emeralds carry the 'jardin' of internal fractures and inclusions that prove their natural origin.
Jewellery, almost exclusively. Emeralds have no significant industrial use — unlike ruby, which powers lasers and bearings, emerald's value is purely ornamental.
Zambia, with roughly 35% of world emerald production by volume (GIA estimates), from the Kagem mine — the world's largest emerald mine. Colombia's Muzo mines produce the finest stones.
China produces negligible emerald. It is a growing consumer market for fine emeralds, particularly Colombian stones, as Chinese jewellery demand expands.
Low. No industrial use, diversified supply across Zambia, Colombia, Brazil, Ethiopia and Afghanistan, and a market that runs on origin and certification rather than volume. No country can leverage emerald supply.

Emerald is green beryl, famed for its 'jardin' of inclusions. Zambia produces the most by volume from Kagem; Colombia's Muzo mines produce the finest stones. With no industrial use and supply spread across five countries, emerald has no chokepoint — its market runs on origin and certification.
