What a karat stamp does not tell you

A karat stamp such as 916 or 22K is a claim someone made about the purity of the metal, not a measurement taken on your piece today. It says nothing about how much your piece weighs, whether stones are set into it, or how much solder was used to join its parts. That is why any careful buyer runs a karatmeter test in front of you before naming a rate, stamp or no stamp.

Does a stamp mean the gold has already been checked?

Not by the person about to pay you for it. A hallmark or a karat number is stamped once, usually when the piece is made, by the manufacturer or the jeweller who sold it. It is a record of what that party said the purity was at that time.

Between then and now, a lot can happen to a piece that a stamp cannot show:

• Wear and repair. A ring resized or a clasp replaced may carry solder that was never part of the original alloy.
• Age. Older pieces, especially anything inherited, often predate BIS hallmarking altogether or carry marks from a system no longer in use.
• Simple error or fraud. Stamps can be worn smooth, copied, or applied to metal that never matched the claim.

None of this means your gold is suspect. It means the stamp is a starting point, not a result. We have written separately about what BIS hallmarking actually proves and does not prove, and about reading 916 and the other marks on your jewellery, if you want the detail on the marks themselves.

What does the stamp leave out?

Even a stamp that is completely accurate about purity is silent on three things that decide what a piece is actually worth at the counter.

Weight. A stamp tells you the alloy is, say, 22 karat. It says nothing about whether the piece is two grams or twenty. Weight is read separately, on a calibrated scale, at the time you sell.

Stones. Any stone set into a piece is not gold, and a karat stamp on the metal has no bearing on it. We test and value the gold only; we do not test, buy, or price stones. If a piece has stones set into it, that weight is worked out separately from the gold weight before anything is quoted.

Solder. Chains, rings with joints, and repaired pieces often carry a small amount of solder that is not the same purity as the rest of the piece. A stamp made when the piece was new does not account for solder added later. A karatmeter reading, taken across the actual metal in front of you, does.

None of this is about assuming the worst of a piece. A hallmark backed by a livexrf or karatmeter check simply moves the piece from "someone's claim" to "what this metal measures today," which is the number a rate can actually be applied to.

Why does the test happen in front of you, even with a stamp?

Because the stamp answers "what was this alloy meant to be," and the test answers "what is this metal, right now, on this scale." Those are different questions, and only the second one can be checked by both sides in the room.

A karatmeter reading taken while you watch means:

• You see the same number the buyer sees, at the same time.
• The reading is taken on your specific piece, not assumed from the stamp.
• Weight is read on the same scale, also in front of you.

Purity from the karatmeter and weight from the scale are the two inputs. The rate for the day is the third. Only once all three are in hand does a figure for your piece get worked out — that is why nobody can tell you what a piece is worth over the phone from a description alone. We have covered the mechanics of that reading, step by step, in a separate post, and how the rate itself moves day to day in another.

If a buyer ever offers to skip the test because "it already has a stamp," that is worth pausing on. A stamp cannot see solder or confirm today's weight; only the test on your piece can. If you want to see how this looks in practice before you commit to a shop, call or WhatsApp 9217742656 and ask any question about the process — how the karatmeter is read, how weight is separated from stones, anything — before you decide where to go.

Questions people ask

Does a hallmark mean I do not need my gold tested? No. A hallmark or karat stamp records a claim made when the piece was made or sold; it does not measure the metal in front of you today. A karatmeter test, done while you watch, checks the actual purity of your specific piece.

Can two pieces both stamped 916 be worth different amounts? Yes, once weight and any stones are accounted for. A stamp only states purity; the weight of the gold and whether stones are set into the piece are read separately at the counter before a figure is worked out.

What if my gold has no stamp at all? It can still be sold. A karatmeter reading tells a buyer the purity directly, stamp or no stamp, which is exactly why the test matters more than the mark.
