Identifying Emerald Fakes and Lab-Created Stones: A Guide

In the captivating realm of gemstones, a significant development took place in the 1960s that redefined the identity of one of the most iconic gems – the emerald. After years of lobbying and discussion, green beryls were officially recognized as "natural emeralds."

This recognition was based on a crucial factor: the presence of chromium and/or vanadium as the primary coloring agents. These trace elements, often accompanied by minor amounts of iron, are what give emeralds their distinctive green hue, differentiating them from other types of beryl, such as aquamarine or the colorless goshenite.

If chromium or vanadium is absent, the beryl will not be classified as an emerald but rather as another variety, such as goshenite. The presence of these elements is natural and occurs due to the unique geological formation conditions of emeralds in specific host rocks and tectonic environments.

The identification of green beryls as "natural emeralds" was a significant development in the gemological field. However, this classification is still disputed by some purists, who argue that emerald should only refer to the mineral beryl that forms under specific conditions in the Muzo district of Colombia.

The debate surrounding this topic can be traced back to the discovery of green beryls colored by vanadium in Brazil. This discovery sparked a long-running disagreement, with gemologists like Hanni (1992) and Ward (2001) being involved in the discussion.

Despite the ongoing debate, the presence of chromium or vanadium as the primary coloring agent is essential and definitive for classifying a green beryl gemstone as a natural emerald. These allochromatic gemstones, with their captivating green hue, are considered natural emeralds, assuming no synthetic or treated origin.

In summary, a green beryl must contain chromium and/or vanadium as the primary coloring agent to be classified as a natural emerald. This recognition by the Gemological Institute of America (GIA) in 1963 revolutionized the gemological world, expanding the definition of emerald and broadening the possibilities for this iconic gemstone.
