Gold jewellery is one of India's largest household savings instruments — an estimated 25,000 tonnes of gold is held in Indian homes, worth tens of lakhs of crores of rupees. Yet every year, thousands of buyers are cheated through sophisticated fraud techniques that exploit knowledge gaps, trust, and the social dynamics of jewellery shopping. This comprehensive guide arms you with the knowledge to walk into any jewellery shop in India — from a trusted chain store to a local market — and buy with complete confidence.
Understanding Gold Purity Numbers: Your First Line of Defence
The single most important knowledge a gold buyer must have is the purity numbering system. In India, gold purity is expressed in parts per thousand and marked as a three-digit number on hallmarked pieces. These numbers directly correspond to the karat (K) system used colloquially.
| Purity Mark | Karat | Gold Content | Common Use | IBJA Rate Basis |
|---|---|---|---|---|
| 999 | 24K | 99.9% | Coins, bars, investment gold | Full rate × 1.000 |
| 958 | 23K | 95.8% | Rare in India | Full rate × 0.958 |
| 916 | 22K | 91.6% | Standard jewellery — most common in India | Full rate × 0.916 |
| 875 | 21K | 87.5% | Middle East market | Full rate × 0.875 |
| 750 | 18K | 75.0% | Diamond/gemstone jewellery, rose gold | Full rate × 0.750 |
| 585 | 14K | 58.5% | Harder, more durable jewellery | Full rate × 0.585 |
| 375 | 9K | 37.5% | Common in UK/Europe; rare in India | Full rate × 0.375 |
Weight Fraud: The Most Costly Type of Gold Cheating
Gold is priced by weight, making weight measurement the most direct and impactful fraud vector. Several techniques are used to defraud buyers on weight.
Hollow Jewellery Without Disclosure
Chains, bangles, and some necklaces are sometimes constructed with hollow interiors to achieve a large visual size at reduced gold weight. This is not inherently fraudulent if disclosed — hollow gold jewellery is a legitimate product category. Fraud occurs when a jeweller charges you for the apparent volume weight rather than actual weight, or fails to disclose the hollow construction when asked about durability and resale value. Always ask for the exact weight in grams shown on the bill, and compare it with your own observation on a balance scale.
Stones and Lac Counted in Gold Weight
In traditional Kundan, polki, and Meenakari jewellery, the piece contains enamel (meena), lac (a resin used as backing), and stones. These non-gold materials add weight. Dishonest jewellers weigh the complete piece and charge you the gold rate for the full weight. Your invoice should clearly state the gold weight separately from the gross weight. Ask explicitly: "What is the net gold weight in grams, excluding stones and other materials?"
Inaccurate Scales
While rare in established shops, market-stall sellers may use calibrated weights fraudulently — showing a piece as heavier than it is. The legally mandated standard for jewellery weighing is the "0.001g precision electronic scale" calibrated under the Legal Metrology Act. You have the right to ask for the piece to be weighed on a calibrated scale in front of you, and to verify with your own scale if you have access to one.
Making Charges: Hidden Costs and Manipulation
Making charges are the legitimate cost of craftsmanship added above the raw gold value. However, several manipulations are common:
Wastage Charges
Some jewellers add a "wastage" charge of 3–8% on top of making charges, claiming gold is lost in the manufacturing process. For pre-made pieces already sitting in the display case, wastage has already occurred and should be factored into the making charge, not added separately. Wastage charges are only legitimately applicable to custom-made pieces. For off-the-shelf jewellery, refuse wastage charges and ask for them to be included in the stated making charge.
Excessive Making Charges on Simple Pieces
A plain gold bangle requires minimal craftsmanship. Making charges of 3–7% are reasonable. Making charges of 20% on a plain bangle are exploitative. Know typical making charge ranges: plain pieces 3–8%, basic design 8–15%, handcrafted intricate work 15–25%, highly specialised work (polki, meenakari) 25–40%. Any making charge significantly above these ranges for the design type should be questioned and negotiated.
HUID Verification: Your Definitive Fraud Check
Since 2022, every BIS-certified gold piece carries a 6-character HUID (Hallmark Unique Identification) laser-etched on the piece. This is your most powerful fraud protection tool:
- Download the "BIS Care" app from the Google Play Store or Apple App Store (official app by Bureau of Indian Standards)
- In the shop, ask to see the hallmark on the piece — it will be a small triangle (BIS logo) followed by the three-digit purity number and the 6-character HUID
- Enter the HUID in the BIS Care app
- The app shows: registered jeweller's name, BIS licence number, assaying centre, metal, purity — all in real time from the BIS database
- If the jeweller name shown does not match the shop you are in, or if the HUID does not appear in the database, do not buy the piece
Exchange Fraud: When Your Old Gold Gets Undervalued
The gold exchange or part-exchange system — where you give your old jewellery as partial payment toward a new purchase — is rife with fraud. Common techniques include:
- Claiming lower purity without testing: The jeweller visually "assesses" your 22K piece and tells you it is only 18K, giving you ₹5,000–₹10,000 less per tola than justified
- Excessive deduction for "impurities": Legitimate testing may find minor alloy variations, but deductions of more than 1–2% from stated purity without written test results are suspect
- Weight deducted for solder and stones: While this is legitimate for kundan pieces, deductions on plain gold items exceeding 0.5–1% are dubious
- "Our rate" being lower than IBJA: If a jeweller uses a rate 2–3% below IBJA for valuing your exchange gold, shop elsewhere
Protect yourself by getting acid or electronic karat testing done on your exchange gold with a written result before agreeing to any exchange terms. Many reputable jewellers offer this for free — unscrupulous ones will resist it.
Online Gold Buying Fraud
Beyond the established platforms (CaratLane, BlueStone, Malabar, Tanishq), a significant number of fraudulent or sub-standard online sellers operate in India. Warning signs:
- No HUID or BIS certification mentioned in product listing
- Gold price significantly below IBJA rate (more than 5% below suggests fraud or drastically substandard gold)
- No physical return address or contactable customer service in India
- Fake review profiles (check review dates — a cluster of positive reviews from new accounts in a short period is a red flag)
- Different item delivered from what was photographed — more common than consumers expect
- No invoice with separate gold weight, making charges, GST breakdown
Tourist Area and Street Market Fraud
Receipt and Invoice Manipulation
A legitimate jewellery invoice must contain:
- Jeweller's name, address, and GSTIN number
- Description of piece (type, weight, purity)
- HUID for each hallmarked piece
- Gold weight in grams
- Gold rate per gram used (should match IBJA rate for that date)
- Making charges (as percentage or flat amount, explicitly stated)
- Stone charges if applicable
- GST at 3% on the taxable value
- Total amount paid
A receipt that simply says "1 gold necklace — ₹45,000" tells you nothing useful for future insurance claims, exchange, or dispute resolution. Demand itemised billing. If a jeweller refuses to provide a proper GST invoice, they are likely operating outside the tax system — do not buy from them, as you have no legal protection for the transaction.

Pre-Purchase Checklist: 20 Points to Verify
- Check IBJA gold rate for the day at ibja.co before entering the shop
- Confirm the jeweller has a BIS licence displayed in the shop
- Locate the hallmark stamp on the piece — find the three-digit purity number
- Find the HUID (6-character code) on the piece
- Verify HUID on BIS Care app — confirm jeweller name matches
- Weigh the piece on the shop's scale with you watching; note the weight
- Ask explicitly: "What is the net gold weight, excluding stones and lac?"
- Ask: "What making charges percentage are you applying?"
- Ask: "Are there any wastage charges? If so, justify for a pre-made piece."
- Calculate the expected price: (gold weight × IBJA rate × purity factor) + making charges + 3% GST
- Compare your calculation with the quoted price — a difference above 5% demands explanation
- Request an itemised invoice with GSTIN, HUID, and all charges broken out
- Confirm the gold rate used on the invoice matches IBJA rate
- Check the invoice date and time (backdated invoices are sometimes used for tax evasion)
- If exchanging old gold, demand acid test or electronic karat test with written result
- For exchange, confirm the jeweller is using IBJA rate for valuing your old gold
- Ask about return and exchange policy — get it in writing if possible
- Pay by digital means (UPI, card) for chargeback rights rather than cash
- Photograph the hallmark stamp immediately after purchase
- Save invoice digitally immediately — do not rely on paper alone
Frequently Asked Questions
What is the IBJA gold rate and how do I find it?
The India Bullion and Jewellers Association (IBJA) publishes the daily wholesale gold rate used by the jewellery industry as the standard reference. Check it at ibja.co — it is updated twice daily (morning and evening). This is the rate before GST, making charges, and retailer margin. Retail prices will always be above this, but the IBJA rate is your anchor for calculating fair price.
Can a jeweller refuse to show me the hallmark on a piece?
No. Under mandatory hallmarking rules, any licensed jeweller selling gold must have BIS-hallmarked pieces and must provide the HUID on the invoice. Refusing to show you the hallmark or claiming there is "no space" for a hallmark on the piece are serious red flags. Small pieces under 2 grams may have hallmarks in a less visible location, but they must be present.
Is it safe to buy gold from an unlicensed shop?
No. Unlicensed sellers are outside BIS's mandatory hallmarking framework and have no legal accountability to you. Purchasing from them gives you no recourse through consumer forums and no BIS protection. You may save 1–2% on making charges but risk buying substandard gold with no remedy if something is wrong.
What should I do if I realise after buying that the gold is wrong purity?
First, get an independent assay test from a BIS-accredited assaying centre (you can find these on bis.gov.in). This provides legally valid proof of purity. With this proof, approach the jeweller for a full refund. If refused, file a complaint with BIS (via BIS Care app) and the District Consumer Disputes Redressal Commission. For amounts above ₹1 crore, cases go to the State Consumer Commission.
