I have been told to wear a 5 carat ruby and the shop gave me its own certificate. The price is ₹65,000. What should I check before I pay?
Two things, in order. First, share your birth details so I can tell you why a ruby was suggested and whether I agree. Second, ask for a report from an independent lab that you can verify on its own website. Do not pay a deposit today.
Short answer
Before you buy a gemstone, ask an astrologer why that stone, then check the stone itself: an independent lab report you verify on the lab's own site, a named treatment, a fair price and a written return policy. A GIA identification report for a stone under 2 carats costs ₹7,110 1. Never buy under pressure. On Kismo, verified astrologers explain the reasoning online from anywhere, and sell no stones.
What are the key facts about before you buy a gemstone?
| Answer | |
|---|---|
| First question | Why this stone, by which rule, and does the person suggesting it earn from the sale |
| What a lab report shows | The type of gem, natural or laboratory-grown, and any detectable treatment 1 |
| Lab fee | GIA India: ₹7,110 for an identification report on a ruby, sapphire or emerald under 2 ct, from 1 July 2026 1 |
| Indian lab | Gemmological Institute of India, Mumbai, set up in 1971, with online report verification 2 |
| Common trap | Glass-filled rubies are commonly seen, and the filling makes low-quality material sellable 3 |
| Red flags | A deadline, a seller who is also the adviser, no verifiable report, no written return policy |
| Session on Kismo | From ₹15 a minute, 5 free minutes in the first session, online from anywhere in India and abroad |
What should I check before buying a gemstone for astrology?
Before buying a gemstone for astrology, check the advice first and the stone second. Kismo is an app where you talk to verified Vedic astrologers by chat or call, in 16 languages.
- The reason. Ask which planet the stone stands for and why your chart needs it; the gemstone advice page explains the rules astrologers use.
- The report. A GIA colored stone report states the gem type, whether it is natural or laboratory-grown, and any detectable treatment 1.
- The lab. Verify the report number on the lab's own website; the Gemmological Institute of India offers a 'Verify GII Report' tool 2.
- The treatment. Ask in writing whether the stone is heated, oiled or glass-filled; GIA notes glass-filled rubies are commonly seen 3.
- The price and the return policy. Compare at least two sellers and get the return and buy-back terms on paper before paying.
What changes the checks when I am about to buy a stone?
- Who suggested it. Advice from someone who also sells the stone needs a second opinion from someone who does not.
- The size and price. Above a few carats, a lab report costs a small share of the price; on a cheap stone the ₹7,110 fee can cost more than the stone 1.
- The kind of stone. Ruby, sapphire and emerald get identification and origin reports at GIA; origin adds to the fee, ₹8,530 under 2 ct 1.
- Whether you already bought it. A stone you own can still be tested; the question then is whether to wear it, not whether to buy.
How much does a gemstone lab report cost in India?
A GIA identification report for a ruby, sapphire or emerald in India starts at ₹7,110, for stones under 2 carats. These are GIA's rupee fees from 1 July 2026, for loose or mounted stones 1.
| Stone weight | Identification report | Identification and origin report |
|---|---|---|
| 0.01 to 1.99 ct | ₹7,110 | ₹8,530 |
| 2.00 to 3.99 ct | ₹8,530 | ₹11,375 |
| 4.00 to 5.99 ct | ₹9,955 | ₹14,220 |
| 6.00 to 7.99 ct | ₹12,325 | ₹19,910 |
| 8.00 to 9.99 ct | ₹14,695 | ₹26,070 |
Fees for ruby, sapphire, emerald and similar stones; coral and other materials under 15 ct also start at ₹7,110 1. Other labs charge their own fees, so ask the seller which lab and check that lab's price list.
What goes wrong when people buy gemstones for astrology?
Treated stones are the most common surprise. GIA's lab notes say glass-filled natural rubies are commonly seen, and that the filling can make low-quality material marketable 3. Under magnification the filled cracks show a blue and orange flash, so a lab finds it easily 3.
Prices move fast, which makes a 'today only' price hard to judge. In 2024 the gem export council's magazine reported a 25% rise for tanzanite and nearly 50% per carat for Australian South Sea pearls, with multicolour tourmalines at ₹5,000 to ₹7,000 a carat 4. It also noted large glass-filled rubies selling well 4.
Fraud sold as spiritual help is real. In a Nashik case reported in October 2026, a trader allegedly gave three gold rings of 20 grams and ₹2.62 lakh for a ring 'energised' with a mantra 5. Its stones were later found to be worth about ₹5,000 5.
A Kismo astrologer can help with the first question, why a stone and which one, and can tell you when no stone is needed. An astrologer cannot certify a gem, value it or guarantee a result; a lab and a written receipt do that.
What should I ask before I pay for a gemstone?
Ask these questions before paying for any gemstone. If any answer is no, wait and get a second opinion.
| Question | Why it matters |
|---|---|
| Can the adviser explain which planet and which rule, in plain words? | A stone named without a reason cannot be checked |
| Is the adviser free of any share in the sale? | Advice and selling together is a conflict of interest |
| Is there a report from an independent lab, verifiable on the lab's own site? | A shop's own certificate proves little 2 |
| Does the report name any treatment, such as heat or glass filling? | Treatment changes the value a lot 3 |
| Have you compared the price with at least two other sellers? | Trade prices change from year to year 4 |
| Are the return and buy-back terms in writing? | A verbal promise is hard to enforce |
| Is there no deadline, discount for paying today or extra fee for 'energising'? | Pressure is the clearest sign of a bad sale 5 |
What do people get wrong about this?
Belief: A certificate from the shop is enough proof.
A certificate is only as good as the lab behind it. Use a lab that lets you verify the report on its own site, such as GII's report verification tool 2.
Belief: A heated or glass-filled stone is the same as a natural one.
A lab report names detectable treatments 1. Glass filling hides fractures in low-quality ruby, and GIA says it is easy to detect under magnification 3.
Belief: A stone must be 'energised' by the seller, for a fee, before it works.
No study shows any stone changes outcomes, energised or not. In the Nashik case, a ring sold as charged by a mantra held stones worth about ₹5,000 5.
Before you pay anyone
How do you know an astrologer is genuine?
- Every Kismo astrologer passes four steps: qualification review, panel interview, live audits of real sessions, 30-day probation.
- Nobody can guarantee an outcome. Treat any promise of a fixed result as a red flag.
- Never pay for an expensive puja or ritual under pressure. Get a second opinion first.
- On Kismo you only pay for the minutes you use; misconduct, pressure or a request for money outside the app is handled by a person.

What should I know before booking a session about before you buy a gemstone?
| Question | Answer |

Questions people ask
How do I verify a gemstone lab certificate online?
Verify a gemstone certificate on the lab's own website, by typing the report number yourself, never through a link the seller sends. GII in Mumbai offers a 'Verify GII Report' tool for this 2. If the lab has no way to check a report, treat the certificate as a sales paper, not proof.
What does a gem lab report tell me about my stone?
A gem lab report tells you what the stone is, whether it is natural or laboratory-grown, and whether it has a detectable treatment. GIA's reports also give the cut, shape, weight, measurements, colour and a photograph, and an origin report adds the country when it can be told 1. A report does not value the stone.
Is a glass-filled or heated ruby still a real ruby?
A glass-filled ruby is ruby material whose cracks are filled with glass, and GIA says such stones are commonly seen 3. Heating is a separate treatment. Both should be named on the report and reflected in the price. Ask the seller in writing which treatments the stone has had.
Can I check if a gemstone is real at home?
Home checks such as scratching or water tests cannot reliably tell a natural stone from a synthetic or treated one, and scratching can damage it. Even the Garuda Purana leaves the judging of a gem to an expert who knows the gem books 6. Use a lab: GIA's basic report starts at ₹7,110 in India 1.
Can a Kismo astrologer tell me whether a stone I already bought suits my chart?
Yes, a Kismo astrologer can read your chart and say whether the planet behind the stone fits your question. You pay from ₹15 a minute, one rate for chat and call, and the first session has 5 free minutes with no card needed. The astrologer cannot test or value the stone; a lab does that.
The astrologer who suggested my gemstone also wants to sell it to me. Is that a red flag?
Yes, advice and sale from the same person is a conflict of interest and a red flag, especially with a deadline. Get a second opinion before paying for any stone or ritual, and buy only with a verifiable lab report. On Kismo, an astrologer who pushes a sale or asks for money outside the app is handled by a person.
