About the origin
A source worth understanding
Discover Nigerian emeralds
Nigeria is known for exceptional coloured stones. Its emerald story is less familiar—and still being written.
Colombia may dominate emerald history, while Zambia has become one of the modern gemstone industry’s most important producers. But emerald occurs in varied geological environments around the world, and Nigeria is an origin attracting increasing interest.
Nigerian material can range from pale mint and green beryl through to more saturated green and bluish-green material. That range makes careful identification particularly important.

Built for collectors
Individual stones presented with the detail their character deserves.
The collection
Featured Nigerian emeralds
Every stone deserves a permanent, transparent record.
Our first collection is being photographed and documented. No invented weights, treatments or provenance claims are used to fill the catalogue. When published, each listing will distinguish laboratory findings from supplier provenance.

Hue, tone, saturation and zoning all matter. The name “emerald” is not earned by a country label alone.
Understand colour →Where are Nigerian emeralds found?
Published accounts describe occurrences in central Nigeria. Nasarawa has received particular attention for facetable material, while newer green beryl from Nasarawa Eggon shows striking colour zoning.
Explore the map →Nigerian emerald geology
Beryl-bearing pegmatite systems set the regional stage. Trace elements and the local geological environment shape the colour story.

The boundary is more nuanced than a single chromium result. Colour and laboratory convention matter.

“A specialist record of an emerging origin, built one verified stone and one useful observation at a time.”
The project combines gemmological education, original research and commercial enquiries without blurring the boundaries between them.
