Your resale offer is normally based on verified net precious-metal weight, the purity accepted by the buyer, the rate used at that time and any stated deductions—not simply the amount on your original invoice.

What determines a gold jewellery resale offer?
A buyer is primarily valuing the recoverable precious metal. Four parts of the transaction usually matter:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Purity: the karat and fineness claimed for the article, and the purity accepted after verification.
- Net precious-metal weight: the gold weight after excluding stones, enamel, lac, thread, clips or other non-gold parts under the buyer’s method.
- Rate basis: the gold-price reference and the time at which the buyer locks that rate.
- Transaction terms: testing, melting, stone or other deductions, plus whether the quote is for cash or exchange.
A useful way to understand the offer is:
Indicative metal value = net gold weight × accepted purity fraction × applicable gold rate
#1 Best Overall
The final amount can be lower if the buyer applies disclosed deductions or uses a different purity and weight assessment. The original invoice total can also include making, wastage, taxes and other charges that do not represent gold content.
How purity changes the metal value
Karat and fineness are claims about composition
A karat mark and a fineness number describe how much gold the article is claimed to contain. Fineness is expressed in parts per thousand, while karatage expresses purity on a 24-part scale. A higher purity mark means more gold is represented by each gram, assuming the same net weight and the same rate basis.
Purity is only one input. Two pieces with the same marked karat can produce different offers if their net weights differ, if one contains more removable non-gold material, or if a buyer’s test does not confirm the mark. Conversely, a heavier lower-purity piece is not automatically worth less than a lighter higher-purity piece.

When you bought the jewellery, you may have paid for design work, labour, wastage allowances, taxes and retail overhead in addition to the gold. Resale valuation separates those purchase costs from the metal represented by the item. Do not multiply your invoice total by a guessed resale percentage; ask the buyer to show the weight, purity, rate and each deduction used to reach the payable amount.

What an Indian BIS hallmark proves—and what it does not
The three marks on a current BIS gold hallmark
BIS’s General Hallmarking FAQ describes three elements for gold:
- the BIS logo;
- the article’s purity in caratage and fineness; and
- a six-digit alphanumeric Hallmark Unique Identification (HUID) number.
The mark is evidence that the article was processed through the BIS hallmarking system with a declared purity. It is not a promise that a jeweller will buy the piece for the original invoice value, reimburse making charges or use the same deduction policy as another buyer.
Check the HUID in BIS CARE
Consumers can enter the six-digit HUID in the BIS CARE app to check the associated hallmark information. This is a useful identity and record check, especially when comparing the mark with the article and your invoice.

A copied, damaged or disputed mark requires an appropriate purity assessment. A loupe can help you read a stamp, but it cannot authenticate the metal composition or independently validate the HUID record.
Use magnification only to inspect the visible mark
BIS’s Common Consumer Hallmarking FAQ says a jeweller should have a magnifying glass with at least 10× magnification available to show a hallmark. That helps you inspect small characters. It does not turn visual inspection into an assay.
Can people sell their old jewellery to jewelers after Hallmarking becomes mandatory?
Yes. BIS consumer guidance says people may sell old hallmarked or unhallmarked jewellery to jewellers. Mandatory hallmarking does not make an older unhallmarked item unsellable. The buyer may require testing, may value it using a different verified purity, and may apply transaction-specific deductions. Those terms should be stated before the metal is altered or melted.
Will I get my making charges back when I sell gold jewellery?
There is no universal BIS rule that makes making charges recoverable on resale. Making charges pay for fabrication and design at the time of purchase; they are separate from hallmarking charges and from the gold content. A buyer may offer an exchange benefit or a store-specific adjustment, but that is a commercial term rather than a guaranteed recovery.

Do not confuse hallmarking charges with making or wastage charges
BIS’s Common Consumer Hallmarking FAQ asks, “Does Hallmark charges include making charges and wastage charges?” Its answer is: “No”. Hallmarking charges are a distinct line from making and wastage charges. The distinction matters when reading an invoice and when asking what, if anything, a buyer will credit at resale.
Rank #4
What the invoice should show
BIS guidance says the bill for a hallmarked precious-metal article should identify the article, state the net precious-metal weight, state purity in carat and fineness, and show hallmarking charges. Keep the invoice because it helps establish what was sold and supports a complaint or dispute. It still does not convert the original retail total into a guaranteed resale price.
How to compare two resale or exchange offers
Quotes can differ because buyers use different rates, tests, weight methods and transaction conditions. Compare the final payable amount only after normalising these fields:
| Comparison point | Question to ask | Why it changes the result |
|---|---|---|
| Purity basis | Are you using the hallmark and HUID, a physical test, or both? What purity will you accept? | A lower accepted purity reduces the gold quantity credited. |
| Weight basis | What is the net precious-metal weight after removing stones and other parts? | Gross jewellery weight can overstate recoverable gold. |
| Rate basis | Which gold-rate reference applies, and at what time is it fixed? | Different references or timestamps produce different rupee values. |
| Deductions | Are testing, melting, stone removal or other deductions applied? State each in rupees or by method. | Even the same metal value can lead to different net offers. |
| Transaction type | Is this a cash sale or an exchange? What conditions attach to each? | Exchange incentives may not be available for cash, or may require a new purchase. |
| Documentation | Will you provide a written quote and an itemised receipt? | A record lets you compare offers and resolve disagreements. |
These are practical questions for an individual transaction, not a universal BIS deduction formula. Ask every buyer to answer them before you accept the quote.
A step-by-step process for selling or exchanging jewellery
- Gather your documents. Take the original invoice, any certificate and photographs of the hallmark. Note the item description and any stones or detachable parts.
- Inspect the visible hallmark. Ask to see the marks through the jeweller’s available 10× magnification. Record the purity mark and six-digit HUID without treating the stamp alone as proof.
- Check the HUID. Use the BIS CARE app and compare the displayed information with the article and invoice.
- Ask how the buyer will test it. Clarify whether the buyer relies on the mark, performs an instrument test, or sends the item for another assessment. Ask whether testing is chargeable and whether the article will be melted or altered.
- Agree the weight method. Confirm the gross weight, excluded parts and resulting net precious-metal weight. If stones are present, ask how they are removed or valued.
- Fix the rate basis. Have the buyer write down the reference rate, purity rate and timestamp used for the quote.
- Request both transaction versions. If you are considering new jewellery, ask separately for the cash-sale amount and the exchange amount, including any purchase conditions.
- Get the final amount in writing. The quote should show purity, net weight, rate, every deduction and the amount payable. Compare the complete net offers from more than one buyer where practical.
- Approve any irreversible step only after agreement. Do not authorise melting, stone removal or permanent alteration before you understand the test result and the price.
What to do with an unhallmarked or disputed item
Unhallmarked does not mean “no value”
An old unhallmarked item can still be sold to a jeweller. Because it lacks the BIS mark and HUID route, the buyer may place more weight on physical testing, documented provenance and the net-metal calculation. Obtain the method and result rather than accepting a bare percentage deduction.

Use a BIS-recognized Assaying & Hallmarking Centre when purity is disputed
BIS says a consumer may submit jewellery or a sample to a recognized Assaying & Hallmarking Centre for chargeable testing. The centre issues an assay report. Ask in advance about the current fee, the sample required, identification of the item and whether the test will leave any visible or physical change.
Testing is particularly useful when a buyer disputes a hallmark, when an inherited piece has no paperwork, or when competing offers quote materially different purities. The assay result is evidence about the tested material; it does not itself set a resale price.
Protection when a hallmarked article is below its marked purity
BIS consumer material cites section 49 of the BIS Rules, 2018 for a hallmarked article sold as a particular purity but found below the marked purity. The described compensation is two times the amount of the purity difference calculated for the weight of the article sold, plus testing charges.
This is a remedy for a verified purity shortfall in the circumstances covered by the BIS rule. It is not an ordinary resale deduction table and does not mean every sale receives twice the difference or that making charges are reimbursed. Preserve the invoice, HUID details, test report and communications if you believe the marked purity was not met.
Common mistakes that reduce clarity—and how to avoid them
- Using gross weight as gold weight: insist on a net precious-metal figure and an explanation for exclusions.
- Treating the hallmark as a price guarantee: use it as an identification and purity-verification route, then compare the buyer’s rate and deductions.
- Assuming making charges are a recoverable asset: ask for the buyer’s written cash and exchange policy; BIS does not establish one universal credit.
- Relying on a visual stamp: check the HUID in BIS CARE and seek chargeable assay testing when composition is disputed.
- Accepting an unexplained deduction: request the amount or calculation method for testing, melting, stones and other components.
- Comparing headline rates instead of net proceeds: compare the final payable amount after all deductions and conditions.
- Ignoring regional and policy limits: the BIS evidence here is specific to India; hallmark systems and resale practices elsewhere may differ.
Questions to ask before signing the receipt
Before handing over the jewellery, confirm that the receipt records the item, accepted purity, net precious-metal weight, rate reference and timestamp, deductions, transaction type and final amount. Keep a copy of the receipt, the invoice and any assay report. If the item is being exchanged, ensure the receipt separately identifies the old-gold credit and the new purchase charges so the apparent benefit is not confused with a cash-sale value.
