An emerald is typically green, ranging from bluish-green to a pure, deep green.
The most prized emeralds exhibit a bluish-green or pure green hue. This desired green should not be overly dark in tone. High-quality emeralds also demonstrate even color distribution throughout the gemstone. It's important to note that the exact shade of green can vary depending on the emerald's origin, as emeralds mined in different locations can display slightly different colors.
