ಹೀರಾ is the gemstone of ಶುಕ್ರ. It is classically recommended for ವೃಷಭ, ಮಿಥುನ, ಕನ್ಯಾ, ತುಲಾ, ಮಕರ, ಕುಂಭ lagna. It should be avoided by ಮೇಷ, ವೃಶ್ಚಿಕ, ಧನು, ಮೀನ lagna. Every other lagna needs the chart read first — the stone amplifies the graha either way.
Also known as: ಹೀರಾ ರತ್ನ · ಶುಕ್ರ ರತ್ನ
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.
Diamond is worn for Venus on a Friday; White Sapphire is the usual substitute, and carries exactly the same caution.
Diamond is Venus’s stone, worn for marital harmony, comfort and refinement. White Sapphire is the substitute most often used where a diamond is out of reach.

Like Yellow Sapphire, Diamond is prescribed far more casually than it should be. Where Venus is a functional malefic it can amplify relationship trouble and loss through pleasure. The substitute carries the same caution — it is the graha, not the price, that decides.
ಸಫೇದ ಸಫಾಯರ · ಸಫೇದ ಟೋಪಾಜ · ಜಿರಕನ
ಹೀರಾ should be avoided by ಮೇಷ, ವೃಶ್ಚಿಕ, ಧನು, ಮೀನ lagna, where the graha is a functional malefic and the stone amplifies exactly what you were trying to correct. Every lagna not listed as recommended needs the chart read first.
The accepted substitutes are ಸಫೇದ ಸಫಾಯರ, ಸಫೇದ ಟೋಪಾಜ, ಜಿರಕನ. 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 ಶುಕ್ರ without amplifying it. ಹೀರಾ is not: a planetary gem strengthens whatever the graha is already doing, so it needs a chart reading first.
