How a gemstone is chosen from your chart
Classical practice strengthens a planet that works for you. The usual starting point is the Lagna (ascendant) lord, then the lords of the 5th and 9th houses: the trikona houses of merit and fortune. Stones for planets that rule the 6th, 8th or 12th house are traditionally avoided, since strengthening them can strengthen difficulties too.
Tirth applies that rule to your chart, lists the stones to avoid with the reason, and flags a stone whose planet is debilitated or combust, where traditions disagree.
How it works
Every tool uses the same chart and the same classical rules as your full Kundli report, so the results always agree with your reading.
Frequently asked questions
Can I wear a gemstone for my Moon sign or Sun sign?
Vedic practice chooses stones from house lordship in the birth chart, mainly the Lagna lord, rather than from the Moon or Sun sign alone.
Why should I avoid some gemstones?
A stone strengthens its planet in every role it plays. If that planet rules the 6th, 8th or 12th house of your chart, tradition cautions against strengthening it.
Should I consult an astrologer before wearing one?
Yes. Gemstones, especially Blue Sapphire, are powerful in tradition; confirm with an experienced astrologer before wearing one.
