What is Gemstones ?
Gemstones, known as Ratnas in Sanskrit, are sacred natural stones that carry the cosmic energy of the planets. In Vedic astrology, the universe is governed by 9 planets (Navagrahas) — and each planet continuously emits specific rays of energy that influence every aspect of human life. Gemstones act as cosmic filters and amplifiers — they absorb the energy of their ruling planet from the universe and transmit it into the body of the wearer.
Unlike ordinary jewellery, a Vedic gemstone chosen correctly for your birth chart works at an energetic level — strengthening weak planets, pacifying malefic ones, and aligning your personal energy with positive cosmic forces. This is why the same gemstone can bring tremendous benefit to one person and cause harm to another — it entirely depends on your unique birth chart.
The ancient Vedic texts, including the Brihat Parashara Hora Shastra and the Garuda Purana, extensively describe the nine primary gemstones and their planetary connections. These are called the Navaratnas — the nine sacred gems — and they form the foundation of Vedic gemstone therapy that Jayant Pandey has practised for over 40+ years.
The 9 Planetary Gemstones — Which One is Right for You?
In Vedic astrology, each of the 9 planets (Navagrahas) rules a specific gemstone. The gemstone you should wear is determined not by your zodiac sign alone, but by which planet is most beneficial in your unique birth chart — your Lagna Lord, the current Dasha period you are running, and the strength of each planet in your horoscope. Here is the complete guide to all 9 planetary gemstones:

Wearing Process of Gemstone

Selection: Purchase a high-quality, natural, unheated, and untreated gemstone from a certified and trusted source with a lab certificate of authenticity
Weight: Ensure the gemstone is of minimum 3 carats in weight — smaller stones have significantly reduced astrological effectiveness
Metal: Set the gemstone in the correct metal as prescribed — Ruby in gold, Pearl in silver, Blue Sapphire in silver, Emerald in gold, and so on
Purification: On the morning of wearing, soak the gemstone ring in raw milk or Gangajal for 20 to 30 minutes to cleanse any negative energies
Energisation: Place the ring before your deity, light incense, and chant the mantra of the ruling planet 108 times to activate the stone
Day and Finger: Wear on the correct finger on the correct day — Ruby on Sunday, Pearl on Monday, Red Coral on Tuesday, Emerald on Wednesday, Yellow Sapphire on Thursday, Diamond on Friday, Blue Sapphire on Saturday
Regular Maintenance: Clean gently every month, re-energise periodically, and avoid wearing during funerals or inauspicious occasions
Frequently Asked Questions related to Gemstones
Gemstones are natural minerals or rocks esteemed for their beauty, durability, and rarity. Cut and polished, they decorate jewelry and are believed to hold metaphysical properties.
Gemstones are categorized by mineral composition, which encompasses several categories such as valuable stones, including diamonds, rubies, and emeralds, and semi-precious stones, that may include amethyst, garnet, and turquoise. The same categories can also be categorized according to origin, color, clarity, and any modifications made to make them appear better.
The carat weight, cut, color, and clarity—often referred to as the "Four Cs"—are the four factors that determine a gemstone's value. A gemstone's value would also be greatly impacted by other elements like market demand, rarity, and place of origin.
To verify or invalidate if the gemstone is a real one or not, various signs are:
Visual Inspection: Since artificial stones are flawless, see if there are any inclusions or natural imperfections.
Light Refraction: Real gemstones shine and refract light differently than imitations.
Test for Hardness: Using the Mohs scale, real gemstones are more resistant to scratches than imitations.
Professional Appraisal: You should definitely seek the advice of a gemologist who is certified to provide an appraisal and verification.Not every gem receives treatment. Many, though, undergo some kind of treatment to increase their attractiveness. Heat treatment, dying, and radiation are examples of common therapies. Given that therapies might raise the price of the stone and the amount of care needed, you should find out what has been done.
