How does a machine know it is gold? 🔬
It does not look at colour, weight, or the stamp. It reads energy.
Hit any material with X-rays and its atoms respond by emitting photons at energies fixed by their own structure. Gold emits at 9.71 keV. Silver at 22.16. Copper at 8.05. Those numbers are properties of the elements themselves - unchangeable, unforgeable, identical in a Roman coin and a modern chain.
The analyzer counts photons at each energy and builds a spectrum. Peaks show which elements are present. Peak sizes show how much of each.
No acid. No scratching. No melting. The piece is unchanged, because photons went in and photons came out.

When gold is expensive, the cost of guessing goes up with it
When gold is expensive, the cost of guessing goes up with it. 📈
Every percentage point of purity you misjudge is worth more today than it was a few years ago. The same 14K-versus-10K error, the same missed plating, the same conservative discount on a good piece - all of it scales directly with the metal price.
That cuts both ways. Overpaying costs more. Underpaying loses sellers who know what they have.
Jewelry Lab verifies purity in 10 seconds, non-destructively, with a printed certificate the customer can see. At current prices, precision is not a refinement - it is the margin.

“That can’t be right. My grandmother bought it as 18 karat.”
Every gold buyer has had this conversation. The analyzer says 10k. The customer is certain, and often genuinely so - they are repeating what they were told, sometimes decades ago.
Arguing does not work. Showing does.
This is the quiet advantage of a screen the customer can see. The reading is not your opinion against their memory - it is a number both of you are looking at. Run it again on a different spot. Let them watch. If the piece is plated, measure a worn edge against an intact face and the difference speaks for itself.
Most people are not trying to deceive anyone. They inherited a story along with the ring, and the story was wrong before it reached them.
The ones who leave satisfied are the ones who saw how you arrived at the number.

Where does an XRF analyzer actually pay for itself? Not where most people assume. 📊

The obvious answer is avoided bad buys. That's real, but it's the smallest part for most shops.

The larger returns come from things that are harder to notice: buying confidently at the top of the range on genuinely good material instead of discounting for uncertainty, closing transactions faster because the number is on screen rather than under discussion, and keeping sellers who come back because they trust how you price.

Our new blog breaks down the full picture - all the mechanisms, not just the dramatic one.

Every jewelry business owner asks the same question before investing in new equipment: How long until this pays for itself? With the Jewelry Lab XRF analyzer — the answer is faster than you think. And the math is simpler than you’d expect. The Cost of Not Having XRF Before we talk about what the...

Handheld or benchtop? The honest answer depends on one question: does the sample come to you, or do you go to the sample? 🤔

Handheld (ProSpector 3) - you go to the material. Outcrops, drill core, scrap piles, incoming deliveries. Battery-powered, weatherproof, 200+ samples a day. Accuracy is excellent for field decisions.

Benchtop (Jewelry Lab, ElvaX) - the material comes to you. A counter, a lab bench, a receiving desk. Better precision, better detection limits, better on small or awkwardly shaped items, and a printed certificate at the end.

Geologists almost always want handheld. Jewelry counters and pawnshops almost always want benchtop. The interesting cases are in between - recyclers, refiners, and QC labs that do both.

Tell us what you're measuring and where, and we'll tell you which one — including when the answer is neither.

The ore they threw away in 1975 wasn't waste. It was uneconomic - which is a different thing entirely. ⛏️

Recovery technology has improved. Gold prices are nothing like they were. Material that didn't justify processing fifty years ago can be worth revisiting today, and Canada has a lot of it sitting in historic tailings facilities across Ontario, Quebec, and BC.

The question is which piles are worth the trouble.

Portable XRF makes that a field question rather than a lab program. Grid the facility, measure across it, and build a grade picture in days instead of months - including the contaminant profile that determines what remediation would cost.

Two answers from one survey: what's recoverable, and what's a liability.

Who on your crew is actually allowed to pull the trigger? 📋

Owning a registered XRF analyzer and having trained operators are two separate requirements. The instrument gets registered once. Operator competency is ongoing — and it's the part that tends to lapse quietly when crews turn over between seasons.

Our new blog covers operator certification for geologists working with portable XRF in Canada: what training is expected, how it works in practice for seasonal field crews, and what to keep on file.

You’ve heard about NRCan certification. Maybe your employer mentioned it. Maybe you saw it in a job posting. Maybe someone told you it’s required before you can operate a portable XRF analyzer in Canada. And then you googled it. And it looked complicated. Radiation safety regulations. Federal re...

Gold-plated, gold-filled, or solid gold? Across a counter, they look identical. 🥇

The difference is enormous. Solid 14K is 58.5% gold throughout. Gold-filled has a bonded gold layer measured in percent of total weight. Electroplating is a coating measured in microns — sometimes fractions of a micron.

Scratch tests and acid can mislead here, because they sample the surface. So does XRF, if you don't know what you're looking at — the beam reads the top layer first.

Jewelry Lab handles this directly: plating detection plus coating thickness measurement. You see not only that the piece is coated, but how thick the coating is — which is what separates a heavy gold-filled piece with real value from flash plating over brass.

Worn edges tell part of the story. The analyzer tells the rest.

Scrap gold arrives as a mixed pile. Somebody has to price it. ♻️

Broken chains, single earrings, dental gold, bent rings, class rings from four decades, watch cases with unclear plating. All of it in one lot, none of it labelled, and a seller waiting for a number.

Averaging down is the usual answer — assume the worst across the lot and price accordingly. It's safe for the buyer and unfair to anyone bringing in genuinely good material.

XRF lets you sort before you price. Each piece verified in seconds, non-destructively. High-karat material gets recognized instead of buried in the average, plated pieces get identified before they're paid for as solid, and the seller sees the reasoning.

XRF cannot detect lithium. So why do lithium explorers carry one? 🔋
Because lithium doesn’t travel alone.
In LCT pegmatites — the hard-rock deposits that host spodumene — lithium mineralization comes with a geochemical signature XRF reads clearly: rubidium, caesium, tantalum, niobium, tin.
The K/Rb ratio in particular is a classic vectoring tool. As a pegmatite becomes more fractionated — more evolved, more likely to host economic lithium — potassium drops relative to rubidium. Track that ratio across an outcrop or a drill program and you’re tracking your way toward the fertile zone.
All of those elements are well within ProSpector 3’s range, readable in seconds at the outcrop.
Canada’s lithium exploration is expanding fast — Quebec, Ontario, Manitoba, and increasingly BC. The pathfinder approach works the same everywhere.
