Jewellery Valuation for Insurance, Explained

What is a jewellery valuation for insurance?

An insurance valuation is a written, signed document that does two jobs. First, it describes the piece precisely enough that someone who has never seen it could source or make an equivalent. Second, it gives a replacement value: what it would cost, at the time of the valuation, to buy that equivalent item new from a retail jeweller in Australia.

It is not the same as a diamond grading report. A report from a laboratory such as GIA or IGI describes the diamond's characteristics and gives no price at all; a valuation puts a dollar figure on the whole piece, including the setting and any side stones. Our guide to the difference between a valuation and a certificate goes through this side by side.

Insurers ask for a valuation for items above a certain value so they can set your premium, confirm what they are covering and, if you claim, replace the piece rather than guess. Each insurer sets its own threshold for when a valuation is required, so check your policy wording.

What should a jewellery valuation for insurance include?

A good valuation reads like a specification. If your piece were lost tomorrow, the document alone should let a jeweller recreate it. Look for each of these:

If a valuation only says something like "diamond ring, approx. 1 carat, white gold" with a number underneath, it gives your insurer very little to work with. How the piece was made matters too: a ring made by hand at the bench takes more labour to remake than a cast one, so a good valuation notes it. Our guide to cast versus hand-fabricated jewellery explains the difference.

Why is an insurance valuation higher than what I could sell it for?

Because it answers a different question. An insurance valuation states retail replacement value: what you would pay a jeweller to buy or make the same piece new. What you could sell it for, its resale value, is usually much lower, because a buyer of second-hand jewellery is paying a trade or second-hand price, not a retail one.

None of these is the "real" value; each suits a different purpose. That is why replacement value vs resale value is a common source of confusion when people first read a valuation. For estates or a property settlement you need a different kind of document entirely: see valuations for estates and family law.

How do insurers use a valuation when you claim?

Most Australian home-contents and jewellery policies give the insurer a choice: replace the item, repair it, or pay you an amount. Many insurers prefer to replace through their own suppliers, which is why the description matters so much. A detailed valuation makes it far more likely that what you get back matches what you lost.

• Agreed value: the policy covers a specific amount you and the insurer agree, often based on your valuation.
• Replacement value: the insurer pays what it costs them to replace the item at the time of the claim, up to your limit. A market-value policy may pay less, allowing for age and wear.
• Item limits: many contents policies cap any single piece of jewellery unless you list it separately.

Policy types and wording vary between insurers, so read the product disclosure statement or ask your insurer how they settle jewellery claims. Our overview of how jewellery insurance works in Australia covers the main policy types and the questions worth asking before you sign.

Does my diamond need a grading report for a valuation?

No, but it helps a great deal. A valuer can grade an unreported stone in its setting, but grading a mounted diamond is less precise: the claws hide part of the stone and the carat weight has to be estimated from measurements. When a stone has a report from a recognised laboratory, the valuer can check the stone against it and quote the report number. Our guide to certified and uncertified diamonds explains why this makes such a difference.

Many diamonds carry a tiny laser inscription of their report number on the girdle, which lets a valuer match stone to report under magnification. Our guide to what a laser inscription does and does not prove explains its limits, and what a grading report leaves out covers the details a valuer still has to judge by eye.

The laboratory also matters, because grading standards are not identical everywhere. A valuer will usually value a stone on how it actually grades, not only on what the paperwork says. See GIA vs IGI vs HRD, the wider comparison of diamond grading labs, and our notes on GSI and EGL reports. If your stone has an IGI or HRD report, our walk-throughs of the IGI natural diamond report and the HRD diamond report show where each detail sits.

How are lab-grown diamonds valued for insurance?

The same way: the valuer describes the piece and states what it would cost to replace with an equivalent laboratory-grown diamond at retail today. The valuation must clearly identify the stone as lab-grown. Lab-grown diamond prices have changed quickly in recent years, which is a good reason to revalue lab-grown pieces more often so the sum insured stays realistic.

If you are not sure whether a stone is natural or lab-grown, a valuer can send it for testing; a grading report from a laboratory will state whether it is natural or laboratory-grown. Diamond origin reports go a step further for natural diamonds by tracing where a stone came from, which some owners like to keep with their valuation.

How often should you revalue jewellery?

Prices for gold, platinum and diamonds move, so a valuation slowly drifts out of date. Many valuers and insurers suggest revaluing every two to three years, and sooner when metal prices have moved sharply, after you have the piece remodelled or resized, or when you add stones. Check whether your insurer specifies an interval.

An out-of-date valuation can leave you under-insured if prices have risen, or paying a higher premium than you need if they have fallen. Our guide to how often to revalue jewellery goes through the triggers in more detail.

How do you choose a jewellery valuer in Australia?

In Australia, anyone can call themselves a valuer, so look at qualifications and process rather than the title alone. Things worth asking:

• Gemmological training: a recognised gemmology qualification, such as a diploma from the Gemmological Association of Australia or a Graduate Gemologist (GIA) diploma.
• Valuer registration: whether they are registered with a professional valuers' body, such as the National Council of Jewellery Valuers, which sets standards for valuation practice.
• Equipment: a proper loupe or microscope, accurate scales, gauges and a way to test metal and identify stones.
• Fees: how the fee is calculated. A flat fee or a fee per item is generally considered better practice than a percentage of the value, which can reward a higher figure.
• Independence: whether they also sell jewellery, and if so how they keep valuations objective.

A valuation done at the time of purchase is common and perfectly normal, as long as the description is thorough and the value reflects real retail replacement cost. Understanding the stone itself helps you read any valuation: start with the certificates and reports hub and keep the jewellery glossary open for unfamiliar terms.

How to get a jewellery valuation for insurance: step by step

1. Gather your paperwork. Bring the receipt, any grading report and any earlier valuation; they speed things up and make the result more precise.
2. Clean and check the piece. A clean ring is easier to grade, and a jeweller can flag loose claws or worn settings at the same time.
3. Ask how the stone will be assessed. Will it be checked against its report, or graded in the setting with estimated weight?
4. Read the draft. Make sure the metal, measurements, stone details and report number are all there and correct.
5. Send it to your insurer. Confirm the item is listed and the sum insured matches the valuation, then diarise the next revaluation.
