Five green stones from Panama’s El Caño and Sitio Conte burials were confirmed as Colombian emeralds, marking the northernmost pre-Columbian emerald finds yet identified in the Americas.
Portable X-ray fluorescence, infrared spectroscopy and photoluminescence linked the gems to Colombia’s Muzo and Chivor belts, indicating they moved through a down-the-line trade network rather than direct exchange.
Several stones had been drilled, cracked or chipped by local craftspeople but were still buried with elites, suggesting the gems retained strong symbolic and likely political value in Coclé society.
Around AD 1000, emeralds and other imported prestige goods disappeared from the region as elite burials ended, a shift researchers say points to a breakdown in long-distance connections.
The team next plans to map the trade routes into Panama using least-cost path modeling and evidence from intermediary sites.
What lost network funneled Colombian emeralds to Panamanian chiefs over 1,000 years ago?
Why were these foreign gems so precious that Panamanian artisans repaired and reshaped them?
