Emerald is the gemstone of Mercury. It is classically recommended for Taurus, Gemini, Virgo, Libra, Capricorn lagna. Every other lagna needs the chart read first — the stone amplifies the graha either way.
Also known as: Panna · Hara Panna
A planetary gem is held to absorb and transmit the radiation of its graha, which is why it is the strongest intervention in the classical set — and the only one that can make things worse. It amplifies whatever the planet is already doing in your chart, so it is prescribed against a reading, never against a wish.

Most charts should not wear Emerald at all. It is prescribed only where the node's dispositor is strong, where it sits in an upachaya house, and for a specific purpose named by a qualified astrologer.
The accepted substitutes are Tsavorite, Green Tourmaline, Peridot, Jade. They carry the same caution as the primary stone: the substitute is cheaper, but it is the graha and not the price that decides whether it should be worn.
The mantra, the weekday fast and the charity are safe for anyone — they address Mercury without amplifying it. Emerald is not: a planetary gem strengthens whatever the graha is already doing, so it needs a chart reading first.
