Read this before buying a stone. The moon-sign ratna above is the common, classical answer to “which gemstone for my rashi”. But the gemstone that is genuinely right for you depends on your whole birth chart — your lagna (ascendant) lord and which planets are functional benefics. A stone that helps one chart can unsettle another. Generate your free kundli first, and consult before wearing a strong stone (especially Blue Sapphire or Diamond) long-term.
