Artículo: Average Age of Colombian Emeralds Found


Average Age of Colombian Emeralds Found

Colombia is world-renowned for the quality and quantity of its emeralds. These precious stones, which have adorned jewelry and luxury items for centuries, are prized not only for their beauty but also for their geological history.

One of the most intriguing questions for gemologists and emerald enthusiasts is: what is the average age of the Colombian emeralds found? To answer this question, we first need to understand how these gems form, how long their formation takes, and explore the oldest emeralds discovered in the country.

How is a Colombian Emerald Formed?

Emeralds form under specific geological conditions that involve the presence of beryllium, chromium, and vanadium. In Colombia, emeralds originate in hydrothermal deposits found in the Eastern Cordillera mountain range. These deposits form when magma cools and releases gases rich in minerals that, upon contact with sedimentary rocks, generate hydrothermal fluids. These fluids infiltrate the fissures of the rocks, where they combine with trace elements like chromium and vanadium, slowly crystallizing to form emeralds.

How Long Does It Take to Form a Colombian Emerald?

The formation of an emerald is a geological process that can take millions of years. In Colombia, emeralds have been forming since the Cretaceous period, approximately 65 to 145 million years ago. The hydrothermal fluids that create these gems can take from thousands to millions of years to slowly deposit the necessary minerals to form a gemstone-quality emerald. This prolonged and complex process contributes to the rarity and value of Colombian emeralds.

What is the Age of the Oldest Emerald Found in Colombia?

The oldest emerald found in Colombia is estimated to be around 65 million years old, placing it in the late Cretaceous period. These ancient gems are of great interest not only to the jewelry industry but also to scientists studying the evolution of the Earth's crust and the geological history of the Andean region.
