Zambia lifts some of the world’s finest emeralds out of the ground, and almost none of the value those stones gain between the pit and the shop window stays in the country. A rough crystal graded near Kitwe is sorted, sold rough, then cut, polished, set and branded in Jaipur, Bangkok or Geneva, where the fat margins live. That distance between extraction and finished luxury is the real investment map for the gemstone economy.

The base is substantial. Kagem, majority-owned by Gemfields with the Zambian state holding the balance through ZCCM-IH, ranks among the largest coloured-gemstone operations in the world, and what the sector returns to the treasury has become a closely watched figure. Gemfields’ own G-factor disclosure on natural-resource revenues tracks how much of every dollar of sales reaches the state through taxes, royalties and dividends — a fair proxy for how thin the domestic slice stays once the rough leaves the gate.

The Rough-to-Retail Gap: Where the Margin Hides

A cut, certified emerald routinely sells for a large multiple of the rough it began as, and today almost every step that adds that multiple happens offshore. Rough is auctioned in Singapore or the Gulf; cutting houses in India and Thailand capture the lapidary margin; setting, certification and retail branding stack value again in Europe. Zambia earns on the first link of a chain whose returns rise sharply further along.

For an investor, the map is legible precisely because the gaps are so wide. Each stage performed onshore — sorting, grading, cutting, setting — retains value that currently exits with the rough. The opportunity is not to displace the whole global chain but to claw back the links that can plausibly be done at home.

The margin is not missing; it is simply being added somewhere else.

The Craft Layer: Cutting, Polishing and Jewellery

Lapidary and jewellery manufacture are skill businesses more than capital businesses, which suits a country with a young workforce and a thin industrial base. A cutting and polishing cluster needs trained hands, reliable power and a trusted supply of rough more than it needs vast factories. Zambia’s constraint has been the first and third: too few certified cutters, and rough that flows straight to export.

This is where policy and private capital meet. A special economic zone geared to gem processing, paired with lapidary training and a domestic-supply obligation on a share of rough, would give a cutting industry both raw material and workers. The Zambia Development Agency’s investment incentives are the natural instrument. The prize is durable, exportable craft employment rather than another extractive rent.

Emeralds are a mineral; cutting them is a manufacturing skill Zambia can own.

Traceability as a Product: Provenance and Brand

In coloured stones, story is price. Buyers increasingly pay a premium for a gem they can trace to a named, responsibly run mine, and Zambian origin already carries weight among emerald connoisseurs. Traceability — a documented path from pit to auction to setting — is not compliance overhead; it is a branding asset that lifts the value of everything downstream.

A Zambian-origin certification, backed by the auction record and mine-level provenance, would let local cutters and jewellers sell not just a stone but a verified narrative. That is the same move luxury coffee, wine and cocoa origins have made: convert a place name into a mark buyers seek out.

Provenance turns geography into a premium — and Zambia has the geography.

The Visitor Economy: Gemstone Tourism

The final link ties the sector to Livingstone and the country’s existing tourism draw. Mine visits, gem fairs, auction-adjacent events and jewellery showcases give high-spending travellers a reason to extend a trip, and give artisanal producers a shopfront. It is modest in scale beside mining revenue, but it monetises the brand rather than the ore.

For an operator weighing where to commit, the sequence is clear: secure rough supply, build the cutting and setting skills, wrap it in verifiable provenance, and let tourism and branding compound the story. Zambia’s emerald opportunity is no longer only in the ground; it is in every stage the country has so far let slip abroad.
