Natural green gemstone emerald, known as "Panna" in Hindi, belongs to the beryl mineral family. Due to its rarity and pure green color, emerald is an extremely valuable gemstone. In Indian Vedic astrology, one of the reasons emerald is considered among the most famous gemstones is because it represents the planet Mercury (Budh Graha). Emerald is believed to bring prosperity, wisdom, and intelligence to a person's life.
The primary sources of emerald gemstones are Zambia, Colombia, and Brazil. Color, clarity/transparency, brightness, and origin are the main criteria used for evaluating the value of emeralds. Depending on the quality, the price of natural emerald gemstones can range from a few thousand to lakhs of Indian Rupees (INR) per carat.
