Gemstone selection — an ancient and effective remedy of Vedic astrology. Each of the nine planets (Navagraha) is associated with a specific gemstone — wearing which increases the planet's grace, pacifies planetary doshas, and brings positive changes in life. However, wearing wrong gemstone can also cause harm — therefore choose gemstone only after kundali analysis.
Tradition of gemstone-wearing is described in Garuda Purana, Skanda Purana, and texts like Ratna Pradeep. For thousands of years, kings, brahmins, sadhakas have been wearing gemstones. Modern science also confirms the effect of specific waves on body through gemstones. In this article, detailed study of 9 planet gemstones, choosing right gemstone, wearing procedure, and precautions.

✦ Choosing Right Gemstone — Scientific Method
Gemstone selection by kundali analysis. Selection by only "lagna" or "rashi" is wrong — see detailed kundali. Main principles: 1) Gemstone of "strongest benefic planet" of kundali (for growth). 2) Gemstone of "weak benefic planet" (to increase strength). 3) Never gemstone of "malefic planet" (destructive).
Planet-strength determination: Planet in exalted sign — strong. In debilitated sign — weak. Own sign or friend sign — medium-strong. Enemy sign — weak. In kendra (1, 4, 7, 10) — strong. In trikona (5, 9) — very strong. In 6, 8, 12 — weak.
Lagna Stone: If lagna-lord favorable — its gemstone best. Example: Aries lagna (Mars) → Coral. Pisces lagna (Jupiter) → Yellow Sapphire. However if lagna-lord in 6/8/12 house — avoid gemstone.
Bhagya Stone: Gemstone of 9th house lord. For fortune-growth. Example: In Aries lagna 9th house lord Jupiter → Yellow Sapphire bhagya stone.

✦ Gemstone-wearing Procedure
Gemstone purchase: 1) Only "Natural" gemstone — synthetic/lab-grown only for fashion, no astrology-effect. 2) "Untreated" — avoid heat treatment or chemical treatment. 3) Certified — IGI, GIA, SSEF certificates. 4) "Eye-clean" — visible clean to eyes, not too many inclusions. 5) Proper size — ratti (1 ratti ≈ 0.18 grams).
Metal: Metal according to gemstone — Ruby/Coral/Yellow Sapphire in gold. Pearl in silver. Emerald gold/silver. Blue Sapphire/Hessonite/Cat's Eye silver or panchadhatu. Diamond gold/platinum.
Muhurat wearing: Day of planet (Ruby Sunday, Pearl Monday, etc.). Shukla Paksha's Dvitiya/Tritiya/Panchami/Saptami/Dashami/Ekadashi/Trayodashi. Pushya/Anuradha/Uttara/Hasta nakshatra. Amrit/Shubh/Labh Choghadiya.
Pre-wearing puja: Wash gemstone-ring with raw milk, Ganga water, panchamrita. Worship of related planet. Mantra (Ruby: "Om Ghrini Suryaya Namah", Yellow Sapphire: "Om Brim Brihaspataye Namah", etc.) 108 times. Brahmin-feeding and donation.
Wearing: Wear in designated finger. Pay attention for first 7-9 days — if "favorable" experience (mental peace, positive events) — keep. If "unfavorable" (restlessness, inauspicious events, illness) — remove immediately. 7-9 day "trial" mandatory especially for Blue Sapphire.
✦ Precautions and Special Rules
Never together: Some gemstones "enemies" — don't wear together. Ruby + Blue Sapphire (Sun-Saturn enemies). Coral + Diamond (Mars-Venus enemies). Emerald + Pearl (Mercury-Moon enemies). Coral + Pearl OK (friends). Yellow Sapphire + everything works.
Blue Sapphire — most dangerous: Blue Sapphire is Saturn's gemstone — extremely powerful. If favorable — unexpected success, wealth. If unfavorable — sudden loss, accident, illness. 7-9 day mandatory trial. Only with consultation of experienced astrologer.
Substitute gemstones: If real gemstone expensive — cheaper substitutes available (less effective but safe). Ruby → Garnet. Pearl → Moonstone. Coral → Carnelian. Emerald → Peridot/Jade. Yellow Sapphire → Citrine. Diamond → White Zircon/White Topaz. Blue Sapphire → Amethyst/Blue Topaz. Hessonite → Brown Garnet. Cat's Eye → Chrysoberyl.
Duration of wearing: Can wear gemstone lifelong. Every 5 years "rejuvenate" gemstone — milk-bath, again mantra-puja. If gemstone breaks — inauspicious sign, change immediately.
For women: Can be worn during menstruation — no obstacle. However if puja-room-rules followed then remove.
