Unique Charm of Colombian Emeralds

For centuries, Colombia has hailed as the most prominent source of top quality emeralds, producing mesmerizing green stones that exhibit rich, saturated and intense colour owing to high levels of chromium and vanadium. However, a great majority of the emeralds found in the market nowadays are treated with oil to enhance their clarity. Natural, untreated Colombian emeralds of considerable sizes are extremely rare and much coveted by collectors and connoisseurs.

This sugarloaf cabochon emerald weighing over 5 carats is an exemplary specimen of this pedigree. Free from clarity enhancement, this fine emerald with its captivating intense colour is further complimented by a mount by Cartier of well-matched proportion.
