A 5,656-Carat emerald discovered at Kagem Mine

A 5,655-carat emerald described as having “remarkable clarity and a perfectly balanced golden green hue” was discovered in Zambia in early October.

The gem was unearthed at the Kagem mine, the world’s largest emerald mine, which is 75% owned by Gemfields Group, a London-based supplier of responsibly sourced colored gemstones, with the remaining stake in the mine owned by government.

The 1.1 kilo grams stone will be sold at an auction in Singapore in November, Gemfields Group Ltd. said in a statement on Monday.

In a rare honor, Gemfields chose to name the gem. In this case, “Inkalamu,” which means “lion” in the Bemba language. The company says the name is in honoUr of the work carried out by two of Gemfields’ conservation partners, the Zambian Carnivore Program and the Niassa Carnivore Projectin Mozambique. 

The stone is almost twice the size of the world’s biggest ever rough diamond, the Cullinan, discovered near Pretoria in South Africa in 1905. Still, it’s unlikely to be worth anywhere near as much since large emeralds are far more common and are hard to value. For years, Gemfields had a pineapple-sized emerald locked in a safe as it didn’t know how much it was worth.

Emerald prices have climbed in recent years as Gemfields boosted advertising in a bid to expand the market for the green stones. Emeralds were previously mainly produced by artisanal miners, leaving retailers without a consistent supply.

Gemfields, which also produces rubies in Mozambique, was taken over last year by South African commodities investment firm Pallinghurst Resources Ltd.
