Gemfields’ Imboo Emerald: A Rare 11,685-Carat Giant
Gemfields (LON: GEM), a leading coloured precious stones miner, revealed the massive 11,685-carat emerald named Imboo, discovered at its Kagem mine in Zambia. This exceptional gemstone, weighing 2,337 grams, exceeds previous record finds at Kagem, including the 2010 Insofu (6,225 carats) and 2021 Chipembele (7,525 carats). Imboo’s vibrant green hue and clarity position it as one of the rarest and largest emeralds ever unearthed globally. The auction runs until September 11, offering investors and collectors a unique chance to acquire this natural marvel.
Imboo’s Geological Significance and Traceability Innovation
The Imboo emerald emerged from the geologically complex Tri-Junction Model, where three rock domains converge, fostering ideal emerald formation. Geologist Dharanidhar Seth and chiseller Justin Banda meticulously extracted the gemstone, preserving its integrity. Gemfields’ partner, Provenance Proof, will apply nanoparticle tagging technology to the stone, ensuring permanent traceability of its Zambian origin even after cutting and polishing. This technology adds value by guaranteeing the emerald’s authenticity and provenance in the global market.
