Every Gemmacol emerald comes with full documentation — including ICG certification and our own Investment Certificate.
Every emerald sold by Gemmacol is accompanied by our Investment Certificate — a formal document designed to support the stone's value as a long-term asset. It records origin, quality characteristics, chain of custody, and our direct assessment of the stone's investment grade — giving buyers the documentation they need to hold, resell, or transfer with full confidence.
All Gemmacol emeralds are certified by the Instituto Colombiano de Gemología, an independent organization that provides reliable, impartial gemological reports and adds value to the gemstone through its expertise. The ICG certification confirms the authenticity, origin, and quality of each stone, providing clients with a recognised baseline of assurance for every purchase.
