What a Jewellery Valuation Actually Says
It is not what the piece is worth. It is what replacing it would cost β and those are very different numbers.

Short answer
A valuation for insurance states the retail replacement cost β what it would cost to buy an equivalent piece today, at retail, in your country. It is deliberately higher than what you paid and much higher than what you could sell it for. It is not an appraisal of resale value, not proof of a good purchase, and not a valuation of the stones in isolation. Its only real job is to tell an insurer what to pay out.
Valuations cause a specific kind of confusion. Someone buys a ring, has it valued, and the document says a number considerably higher than they paid. That feels like confirmation of a bargain. It is not β it is the document doing exactly what it is designed to do.
The three different numbers
| Type | What it states | Used for |
|---|---|---|
| Insurance replacement | Cost to buy an equivalent piece at retail today | Insurance cover. The highest figure. |
| Fair market value | What a willing buyer would pay a willing seller | Probate, division of assets. Much lower. |
| Scrap / intrinsic | Metal weight Γ karat Γ spot price | The genuine floor. Lowest. |
If someone quotes you βa valuationβ without saying which of these it is, the number is meaningless. Most jewellery valuations people hold are the first type.
Why a valuation above your purchase price is not good news. It is very common, and it means one of two things. Either you bought from a maker or direct seller and the valuer priced it against traditional high-street retail β in which case the gap is the retail markup you avoided, not value you gained. Or the valuation is simply generous, which happens because nobody complains about a high number and it is the insurer, not the valuer, who carries the consequence. Either way, a high valuation is not evidence of a good purchase. Anyone presenting it as such is selling you the document rather than the ring.
What a good valuation contains
The number matters less than the description, because the description is what an insurer uses to replace the piece.
- Metal and fineness β stated, and ideally verified rather than read off a stamp.
- Total metal weight in grams.
- Centre stone: dimensions in millimetres, weight, and species. βMoissaniteβ and βlab grown diamondβ must be stated explicitly β a valuation that just says βcolourless stoneβ is not useful.
- Accent stones: count, approximate size, total weight.
- Setting type and construction notes.
- Any grading report number and laser inscription where one exists.
- Photographs β and the valuerβs credentials and date.
A one-line document saying βdiamond ring β $4,000β is close to worthless in a claim, because it does not tell anyone what to replace.
Moissanite and lab grown: the specific issue
Two things to watch, and both are common enough to plan around.
Misidentification. A valuer without the right equipment can describe a moissanite as a diamond, or fail to identify a lab grown stone as lab grown. This matters enormously in a claim: an insurer replacing on the wrong basis is a dispute waiting to happen. Make sure the valuer explicitly identifies the stone, and give them any grading report you have.
Falling replacement cost. Lab grown diamond prices fell steeply between 2020 and 2024. So a five-year-old valuation may state a replacement cost well above what the same specification costs today β which means you may be paying premiums on cover you do not need. Revaluing occasionally can genuinely reduce your premium, which is the opposite of how this usually works.
Do you need one?
- For insurance: usually yes above a certain value, and many insurers require it for a specified item. Check what yours actually asks for β a detailed invoice is sometimes sufficient.
- For a recent purchase: often not immediately. A detailed invoice from the seller, with all the specifications above plus photographs, does much of the same job.
- For an inherited piece: yes β here you genuinely do not know what you have, and identification is the main value.
- For curiosity about resale: a valuation will not tell you this. Ask a dealer what they would pay.
Keeping it useful
Revalue every few years β both because metal prices move and because, with lab grown stones, replacement cost may have fallen. Keep the valuation, the invoice, the grading report and photographs together, and keep a copy somewhere other than your home. A valuation stored in the jewellery box that was stolen is not much help.

Frequently asked questions
Why is my jewellery valuation higher than what I paid?
Because an insurance valuation states retail replacement cost, not what you paid or what you could sell it for. If you bought direct from a maker, the gap is the retail markup you avoided rather than value you gained. Valuations also tend to be generous, since nobody complains about a high figure. It is not evidence of a good purchase.
What should a jewellery valuation include?
Metal and fineness, total gram weight, centre stone dimensions in millimetres with its species explicitly identified, accent stone count and weight, setting type, any grading report number and laser inscription, photographs, and the valuerβs credentials and date. The description matters more than the number, because it is what an insurer uses to replace the piece.
Do I need a valuation for a moissanite or lab grown ring?
Check what your insurer requires β a detailed invoice with full specifications and photographs is sometimes enough for a recent purchase. If you do get one, make sure the valuer explicitly identifies the stone as moissanite or lab grown, since misidentification creates disputes at claim time.
How often should jewellery be revalued?
Every few years. Metal prices move, and with lab grown stones replacement cost may actually have fallen since prices dropped steeply between 2020 and 2024 β so revaluing can reduce your premium rather than raise it. Keep the valuation, invoice, grading report and photographs together, and store a copy away from home.
