Zambia, Colombia, Brazil, as well as Pakistan, Afghanistan, and Madagascar—an emerald’s country of origin significantly influences its characteristics. From the intensity of its color, which may lean toward blue or yellow, to its "jardin," the term referring to the natural inclusions that authenticate the gemstone, each aspect plays a role in determining its rarity and, ultimately, its valuation.

« Emerald » Ring
Sold for €85,800
Auction on July 6, 2023

The only precious stone in the beryl family, emerald is instantly recognizable by its green hue and is found in numerous deposits worldwide. The most prestigious and abundant remains the Boyacá Triangle in Colombia, known for producing the most intense green emeralds. While this origin is the most sought-after, for decades, mine operators have systematically applied heat treatments and oil impregnation to enhance the stones. Today, these factors have become crucial in gemstone valuation, with untreated stones commanding a premium.

In jewelry, emeralds are highly prized in all their shades and cuts but require exceptional care, both in their setting and daily wear. With a hardness ranging from 7.5 to 8 on the Mohs scale (which spans from 1 for talc to 10 for diamond), emeralds are best suited to bezel settings, offering superior protection against shocks. They are also frequently surrounded by diamonds in timeless designs such as the "Marguerite," "Marquise," or "Pompadour" styles.
