carnelianThe Agni Purāṇa recommends thirty-six gemstones for activation of rājayoga for the kings. I guess ordinary mortals can also make good use of these recommendations. The Sanskrit recommendation and our translation is given below.

Vaidūrya Correction

Normally Used but Wrong gemstone. This is not Vaidurya
Normally Used but Wrong gemstone. This is not Vaidurya

It is very interesting to note that ‘vaidūrya’ which was suspected to be cat’s eye gemstone by astrologers for such a long time seems to be quite different. Vedavyāsa specifically uses the word ‘nīla-rakta’ indicating that it is bluish-red in colour. Cat’s-Eye is a feature that can apply to many gemstones including Cat’s Eye Apatite, Cat’s Eye Aquamarine, Cat’s Eye Diaspore, Cat’s Eye Scapolite, Cat’s Eye Tourmaline. Cat’s-Eye simply means a line of light that tilts with the stone. Don’t get carried away with that. What we are looking for is a gemstone which has the blue and red colours blended together.


These thirty-six gemstones are recommended based on the 36 drekkāṇa. For many thousand years the Indians, Persians and the Egyptians have used the drekkāṇa for timing political events and it is evident that this recommendation could be on these lines.


  1. Vaidūrya is actually bloodstone.
    Interestingly, the name is still the same. How come the astrologers overlooked this!

  2. Sanjay Ji,
    I’ve been told to wear 3 carrot Emerald on my little finger. Could you be kind to let me know where in India can I get a real Emerald? Many Thanks Lakshmi

  3. GuruJi, How to find Rajyoga drekkana… arudha? and corresponding Gem stone thereafter.

  4. Guruji,
    So for 1st Drekkana of Aries, the gemstone is Diamond? Could this be linked to Brahmaṛṣi Atri’s advice from Saptarishi Nadi?

  5. Devdatt B.Dave

    Sanjayji,It is written ordinary mortals,can I take liberty of asking for my activation?

  6. Sanjay Ji, Great reference and thank you for unearthing it. One have to wear all 36 or based on D-36?. I wonder how many of these 36 are available in this day & age.


      1. chirag_1980
