Diamond (vajra): Venus's gem, its uparatna, and how to check it
Who it is for
A ratna (and its uparatna) is suggested only for planets that are functional benefics for your lagna: the lords of the 1st, 5th and 9th, and the yogakaraka. Every ratna is shown with its lower-cost uparatna, and the ₹0 options always come first.
Gem suggestions only when the birth time is known; otherwise none, only ₹0 and low-cost options.
No gem for a planet owning only the 3rd, 6th, 8th, 11th or 12th, or for a natural benefic owning only kendras. The lagna lord stays eligible whatever its other house; a trikona lord's trikona ownership prevails over a 6/8/12 second sign.
No gem for children under 12. No gem offer during pregnancy, illness or grief (W12 rule).
The site shows eligibility and information only; whether to wear is the user's choice.
The lower-cost option first. Worn in silver or platinum, on the middle or little finger, on a Friday (uparatna, metal, finger and day: tradition).
When: Friday, Shukla paksha

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.
