Gem Triage: £40

Gem Triage by post: is it a diamond, a moissanite, glass, or a synthetic? £40, in-house

Read our reviews on TrustpilotIndependent written XRF reportA test result, not a UK hallmarkYour item returned tracked, postage includedNo obligation to sell

A first-pass screen for the binary question on a stone: is it a diamond, a moissanite, a glass paste, or a synthetic. Handled in-house by GoldPaid’s gem specialist. Sent in the same parcel as any XRF testing. Honest framing on the report cover.

Will this tell me what my diamond is worth?No. Triage identifies whether the stone is a diamond at all, not what the diamond is worth. Worth depends on the four Cs (carat, cut, clarity, colour) and a full grading report is the right route for that. See the diamond grading page.

You stay in control

A photo on WhatsApp is enough for us to tell you which testing pack fits, what the report can and cannot tell you, and what it will cost. Only when you are comfortable do you order the pack.

No part of this involves a shop visit. The testing service is postal-only, anywhere in the UK, with the phone and WhatsApp answered 8am to 9pm, seven days a week.

Your 14-day cancellation right

Your 14-day cancellation right. This is a service bought at a distance, so you can cancel within 14 days for a full refund. We only start testing sooner if you ask us in writing, which is what lets us report inside 2 to 3 working days, and once the report is finished you can no longer cancel it. Full terms: XRF-pack terms.

What gem triage is, and what it is not

A triage screen is a first-pass identification, not a full grading report. It will tell you with high confidence whether a stone is a natural diamond, a moissanite, a glass paste, a cubic zirconia, or a lab-grown synthetic. It will not tell you the clarity grade, the cut grade, or the colour grade of a diamond, that needs a full grading report.

For full grading on a loose stone, see the diamond grading page. Triage is the right tier when the question is simply "is it real" rather than "how good is it".

How it works in practice

Gem work is handled in-house by GoldPaid’s gem specialist. We are not a UKAS-accredited gemmological laboratory; if you need a UKAS-accredited grading report (for example for a high-value insurance schedule), we will tell you straight and point you at AnchorCert Gem Lab as the escalation route. For most consumer, probate and trade gem questions, the in-house report is the right tool at the right price.

  1. WhatsApp a photo first. The triage starts before any parcel moves. If the photo suggests the stone is plainly costume, we say so and save you the postage.
  2. Combined parcel. If you are also having metal tested, the stone and the metal travel together in one Special Delivery parcel.
  3. In-house identification. Our gem specialist runs thermal, optical and reflective screening to identify the stone species.
  4. Written report. A clear identification result with a plain-English summary, returned with the item.
  5. Item returned by Special Delivery. Same tracked, signed-for return route as the metal-testing service.

What the report tells you

  1. Stone identification headline: e.g. "natural diamond consistent with the visible properties tested" or "moissanite (synthetic silicon carbide)".
  2. Methodology summary: which tests were run and what each result indicated.
  3. Plain-English summary: a single paragraph for a non-specialist.
  4. Recommended next step if the customer wants a graded report from an accredited UK gemmological lab.
  5. Honest limits statement: triage is not grading, and the report says so up front.

How we run the test

  1. WhatsApp the photo. Tell us what you have, what you are trying to confirm, and what you would like the report to cover.
  2. Choose the pack. Single item, family pack, estate pack, probate pack, plating check, or an in-house gem report. Pricing is on the pricing page.
  3. Free tracked label. Special Delivery, tracked, signed for. Print at home or scan a QR at the counter.
  4. Tested at multiple points. A handheld Niton XL2 reads the elemental composition of every item. Plating, low-purity solder joints and unusual alloys are flagged.
  5. Report and return. PDF report inside 2 to 3 working days. Item returned by Special Delivery the same day. Nothing kept, nothing held back.

Postal cover and safety

Your parcel travels on Royal Mail Special Delivery, and Royal Mail cover may be available up to £2,500 depending on the postal method and cover level used, and if a parcel may be worth more than that we split it across more than one prepaid label at no charge, each with its own tracking number and cover.

Tracking begins the moment the parcel is scanned at the Post Office counter. You receive the tracking reference straight after we issue the label, and again the moment the parcel arrives with us.

What you get back, and when

Your item is returned by Royal Mail Special Delivery on the same working day the report is issued. Return postage and its cover are included in the testing fee. There is no separate return charge.

If, for any reason, an item cannot be tested (badly damaged surface, non-metallic core, equipment misalignment), we tell you straight, refund the testing fee, and return the item the same day.

A test, not a sales pitch

The XRF testing service is paid-for and stands on its own. The report is what you bought. Nothing inside it is an offer, an invitation to sell, or a hidden valuation. Nobody running the test has a commission tied to whether you become a selling customer afterwards.

If you separately want a no-obligation offer for the item, you can ask. If you do not ask, nobody chases.

What this report is, and what it is not

This is an independent XRF (X-ray fluorescence) compositional analysis report. It identifies the elemental composition of the item submitted. It is not a UK hallmark and does not replace the legal requirements of the Hallmarking Act 1973. UK hallmarks may only be applied by an authorised UK Assay Office.

The report identifies the elemental composition of an item to the accuracy of the analyser. It does not replace a UK hallmark, an Assay Office fire assay, or a written valuation from a qualified valuer for insurance reinstatement purposes. We say so in plain English on the front page of every report.

If a report leaves any doubt, we will tell you what the next step would be, typically a UK Assay Office fire assay (destructive but definitive) for high-value disputes, or a written insurance valuation from a qualified independent valuer for reinstatement cover.

Why this is a calmer way to sell

Three things make GoldPaid a steadier route than a counter sale. You see a measured valuation in writing, not a verbal estimate. You decide at home, with nobody waiting. And if you decline, the return is free, tracked and signed for, so obtaining the valuation costs you nothing.

Common questions

Will it tell me if my diamond is lab-grown or mined?

Sometimes. Lab-grown diamonds can show fluorescence and strain patterns that screening picks up, but a definitive answer needs specialist instrumentation. Where the screening is inconclusive, the report says so and recommends a full grading or an escalation to AnchorCert for a UKAS-accredited record.

Can the gem be triaged while still in its setting?

In most cases, yes. The triage uses non-destructive screening that works through an open setting. For fully closed bezel settings, removal may be needed; we will flag that on the inbound triage and ask before doing anything.

Is this report UKAS accredited?

No. GoldPaid is not a UKAS-accredited gemmological laboratory. The report is an independent in-house identification. For a UKAS-accredited document (typically required for high-value scheduled insurance under a named-scheme policy), we point you at AnchorCert Gem Lab as the escalation route, with a straight answer on whether your situation needs it.

Do I pay one fee?

Yes. £40 covers the triage in full, including return postage. If you decide afterwards to upgrade to a full grading report, the £85 diamond grading price applies and we credit the £40 towards that upgrade.

Not the question you had? The full GoldPaid FAQ covers the rest, from postal cover and ID checks to what happens if you decline the offer.

Request a prepaid Royal Mail label for your XRF test

Two quick steps. Tell us which pack you want in the box below and we will confirm the price and how to pay before anything is charged. The label itself is prepaid and costs you nothing, and your items are returned to you free once the report is issued. Testing is a separate, paid service: if you are here to sell rather than to have items tested, the assay is free as part of selling and how it works is the page you want.

Two things worth knowing before you start, rather than after. Everyone sends a photo of a UK passport or driving licence, whatever the parcel is worth — it applies to every seller, so it is never a comment on you. And the parcel is handed in at a Post Office counter rather than dropped in a postbox: the receipt they give you is the proof of postage any compensation claim depends on.

Step 1: What are you sending, and how should the label arrive?

A rough description is plenty. This helps us confirm the right postal cover level before we issue the label. Skip if you would rather not say — the field is optional.

How would you like the label to arrive? Both are prepaid and both use Royal Mail Special Delivery Guaranteed, so pick whichever is easier. The QR code is already selected because it needs no printer, and you can change your mind later — just message us before you post.

Choose how your prepaid label arrives

Step 2: Where do we send it?

Your label arrives by email whichever format you chose, so nothing is posted out to you. We need your address because it prints on the label itself, and because it is where anything you decline is returned. UK addresses only.

Needed so the label can be addressed to you.

Would you rather ask a question first, or send a photo? Message us on WhatsApp. It is the fastest way to get a sense of what something is worth before you post anything.
