Every hallmarked ornament in India passed through a laboratory most buyers have never heard of. The AHC full form is Assaying and Hallmarking Centre: the BIS-recognised facility where jewellery is actually tested and stamped, the working end of the entire hallmarking system. Jewellers do not hallmark their own gold. They submit it to an AHC, the centre assays the purity, and only then does the piece receive the triangle, the grade and the HUID that buyers rely on. This guide explains what an assaying and hallmarking centre does, walks the testing process step by step, decodes what the resulting marks show, and covers why AHC-certified purity quietly speeds things up when the same jewellery is later pledged with a lender such as IIFL Finance.

The app never closes, which is exactly why the question feels answerable. If digital gold can be bought at 2 a.m. on a Sunday, surely some hour or weekday must be systematically cheapest? The data's reply is unglamorous: there is no reliable best day to buy gold on the weekly calendar, digital or physical, because the price feeding every app comes from global markets that arbitrage away any predictable pattern. What weekdays do affect is the machinery around the price, spreads, weekend pricing behaviour, and those are worth understanding. This guide covers what actually moves the app's number, what the weekend really does to it, the myths worth retiring, and the one comparison digital buyers skip: unlike the jewellery a lender such as IIFL Finance accepts, app gold can never back a loan.

Buyers often use the two words as if they were rivals. They are parts of one thing. The BIS hallmark is the complete purity certification on gold jewellery, and the HUID is one component of it: the six-character code that gives each piece its own registered identity. So the real question is not hallmark versus HUID but how the code turned the stamp into something you can query from a phone. Understanding what HUID number territory is properly, what the code contains, what it proves, what it cannot, is now basic literacy for anyone buying gold. This guide lays out both concepts, their differences at a glance, the three-step online verification, and where the code fits when jewellery is pledged for a Gold Loan with a lender such as IIFL Finance.

Gold's hallmark became famous. Silver's barely gets mentioned, and most households have no idea their payals and pooja articles could carry one too. The silver hallmark India operates under, run by BIS with its own standard and grades, is voluntary rather than mandatory, which is exactly why so much silver in Indian homes is unmarked, and why the marked pieces deserve more credit than they get. The scheme also modernised recently: since September 2025, hallmarked silver carries a HUID code, the same phone-verifiable identity gold buyers know. This guide explains how the scheme works, the purity grades, the marks to look for, verification, and what certified purity means for silver's value, in a market where the assay discipline mirrors what lenders such as IIFL Finance apply to gold.

One fuels the world and the other calms it, yet their price charts keep glancing at each other. The oil and gold correlation is one of commodity markets' oldest observed relationships: the two often rise together, sometimes for years, then part company without notice. The link is real but indirect, running through inflation, the dollar and investor nerves rather than through any direct use of one in the other. For Indian buyers the connection carries an extra, homegrown twist, since oil and gold sit at the top of the national import bill and squeeze the same rupee. This guide unpacks how the relationship works, the gold-to-oil ratio traders watch, when the link breaks, and why a household planning around gold, including gold pledged with a lender such as IIFL Finance, benefits from watching the oil page too.

Every gram of gold sold in India carries a border toll inside its price, and in 2026 that toll doubled overnight. The customs duty on gold India levies rose from 6% to 15% in May 2026, a sharp reversal of the 2024 cut, announced days after the Prime Minister publicly urged citizens to pause new gold buying to save foreign exchange. Since India mines almost nothing and imports nearly all its gold, that duty flows straight into every rate board in the country. This guide covers the current rate, how the stack of levies actually builds, a worked example, the separate rates air passengers face, and what the duty means for domestic prices, and for households whose existing gold, valued at those higher prices, can back a Gold Loan with a lender such as IIFL Finance.

India never banned buying gold with cash. It made receiving too much of it ruinous, which achieved the same thing more elegantly. The gold purchase limit cash buyers run into is Section 269ST of the income tax law: no person may receive ₹2 lakh or more in cash in a single transaction, day or occasion, and the penalty, equal to the entire amount received, lands on the jeweller. So the counter enforces the ceiling for its own survival. This guide covers how the cap works in practice, the key scenarios, the PAN rule running alongside it, the higher anti-money-laundering threshold jewellers watch, and the question buyers of older, cash-bought gold ask most: can that gold still be pledged for a loan with a lender such as IIFL Finance? It can.

Somewhere between the counter and the rumour mill, buyers picked up the idea that gold now demands Aadhaar at the door. It does not. The question of whether Aadhaar required for gold purchases is settled by one threshold: below ₹2 lakh, no identity document of any kind is needed, and above it, identity is mandatory, with Aadhaar serving as one acceptable answer alongside PAN and the Form 97 declaration. Around that single rule sit the companions worth knowing, the cash ceiling, the jeweller's duties, the hallmark check that protects the buyer rather than the state, and the separate, light KYC when gold is pledged with a lender such as IIFL Finance. This guide walks the full compliance picture in plain terms.

Gold is the last big purchase in India that can still be made with empty pockets, no cards, no forms, provided it stays small. Scale up, or switch routes, and know-your-customer requirements arrive on a schedule worth learning in advance. The rules differ sharply by route: a jewellery counter asks for identity only above thresholds, while KYC for digital gold apps arrives at onboarding, and paper routes like bonds and ETFs demand the full file before the first rupee moves. This guide maps KYC across every gold route, the documents, the trigger points, the jeweller's own duties, and the separate KYC that applies when gold is pledged for a loan with a lender such as IIFL Finance.

One number decides whether a gold purchase is paperless or not, and at 2026 prices that number arrives faster than buyers expect. The PAN card limit for gold purchases sits at ₹2 lakh: cross it in a single transaction and quoting PAN becomes mandatory, whatever the payment method; stay under it and the purchase needs no identity paperwork at all. With gold around ₹1.45 lakh per 10 grams of 24K in early July 2026, the threshold covers barely 13 to 14 grams, a single substantial bangle. This guide works the threshold in detail: how it applies with examples, how much gold fits under it, the separate cash ceiling at the same figure, the Aadhaar alternative, and the quick-reference table, plus what the same documents do at loan time with a lender such as IIFL Finance.
