Cat's eye (vaidurya): Ketu's gem, its uparatna, and how to check it

Who it is for

No gem is suggested for Rahu or Ketu (hessonite, cat's eye): they own no sign and traditions differ. Only ₹0 options are suggested for them; the gem guide gives information only.

Ketu

Information: cat's eye (vaidurya); uparatna tiger's eye

Listing the planets' gems, Praśna Mārga gives vaidurya (cat's eye) for Ketu (in the context of transits). Tradition takes tiger's eye as its uparatna. The site suggests no gem for Ketu, since Ketu owns no sign and traditions differ.

The texts differ

Phaladīpikā (Sastri's translation) gives 'lapis lazuli or turquoise' as Ketu's stone. Gem names and translations vary across texts; this is one more reason the site suggests no gem for Ketu.

How to check a gem or uparatna is genuine

  • First check that the planet is a functional benefic for your chart (gem rule). No gem is necessary; ₹0 options first.
  • No gem replaces medical care.
  • Never buy under pressure or fear. If the astrologer also sells the gem, a second opinion is reasonable.
  • Get a certificate from a recognised lab (e.g. GTL Jaipur, IGI, GIA). Verify the certificate number yourself on the lab's website; the photo, weight and size should match the stone.
  • Natural, synthetic (lab-made) and treated are three different things. Treatments include heat, glass-filling (common in ruby), dyeing and oiling (common in emerald). Get the disclosure in writing: natural or not, and which treatment.
  • Pearl: most pearls on sale are cultured; natural pearls are rare and very costly. Coral: dyed or reconstituted coral is also sold. This should be written clearly.
  • Have the weight written in carats and ratti. As commonly used, 1 ratti ≈ 0.91 carat, but sellers use different ratti values; so the bill must give the weight in carats.
  • Get a bill with the seller's name and address, the stone's name, natural/treated, weight, certificate number and the return policy. Ask about returns before you buy.
  • Uparatnas (e.g. amethyst, citrine, peridot, moonstone) also come real or imitation; have 'natural' written for them too.

Pause and think if you see these

  • '100% real' without a certificate, or a certificate whose number is not found on the lab's site.
  • A promise that the gem will bring money, marriage, a job or health.
  • Fear such as 'harm will come if you don't wear it today'.

If someone sells through fear, 'buy today' or hurry, stop. A genuine purchase can wait and comes with a bill.

Get a proper bill for every purchase: the seller's name, address, GST number (if any), a full description, weight, price and the return policy.

Accept claims like 'abhimantrit', 'siddh' or 'pran-pratishthit' only if the seller states in writing who did it, when and how, and can show a video or photo. Such a claim should not be a reason to pay more.
