Understanding Jewellery Appraisals: What They Mean When You Want to Sell

Key takeaway: A jewellery appraisal is a professional estimate of an item’s worth for insurance, estate or resale purposes. Insurance appraisals state replacement cost, not what a buyer will pay you. To sell gold or diamonds in Johannesburg, you need a fair-value offer based on weight, purity and the live market.

Most people first encounter a jewellery appraisal when they insure a ring or inherit a piece from family. The document looks official, carries a rand figure, and feels like it tells you exactly what your jewellery is worth. When the time comes to sell, though, many sellers in Sandton and across Gauteng are surprised to learn that the appraised value and the price a buyer offers are two very different numbers. Understanding why is the difference between a confident sale and a frustrating one.

This guide explains what jewellery appraisals are, the various types you may come across, why appraised values rarely match resale offers, and how to work out what your gold, diamonds or watches are genuinely worth when you want cash in hand.

What Is a Jewellery Appraisal?

A jewellery appraisal is a formal assessment of a piece, carried out by a qualified appraiser or gemologist, that describes the item in detail and assigns it a monetary value. A typical appraisal records the metal type and purity, the weight, the type and quality of any stones, the craftsmanship, and an estimated value for a stated purpose.

The crucial point that catches sellers off guard is the phrase “for a stated purpose”. An appraisal value only makes sense in the context it was written for. The same diamond ring can carry several different values on paper, and all of them can be correct at the same time.

The Main Types of Appraisal

Knowing which type of appraisal you are holding tells you how much weight to give the figure on it.

Insurance appraisal

This is the most common type and almost always the highest number. It states the retail replacement cost, in other words what it would cost to walk into a jeweller and buy a comparable new item today. Insurers use it to set premiums and pay out claims. It is not what anyone will pay you for a used piece.

Fair market value appraisal

This estimates the price a willing buyer and a willing seller would agree on in an open market, often for estate, donation or division-of-assets purposes. It sits well below the insurance figure and is closer to reality, though it is still an estimate rather than a firm offer.

Resale or liquidation value

This reflects what you can realistically expect to receive when selling, especially when you want payment quickly. For gold items in particular, this value leans heavily on the metal content and the live gold price rather than on craftsmanship or brand.

Why the Appraised Value and the Selling Price Differ

Sellers often arrive at our Illovo premises holding an insurance certificate and expecting an offer to match it. The gap between the two is not a buyer trying to short-change you. It comes down to how each number is built.

• Retail markup. A new piece in a jewellery store carries the cost of design, branding, store overheads, marketing and profit margin. None of that is recoverable once the item leaves the shop.
• Replacement versus resale. Insurance values describe what it costs to replace an item new. Resale describes what the open market pays for it used. These are different economic questions.
• Metal versus sentiment. For gold jewellery, the dominant driver of resale value is the actual weight of pure gold in the piece, measured against the live gold spot price. A worn gold chain is valued for its gold, not its original purchase receipt.
• Condition and demand. Wear, damage, missing stones and current market demand all shape a real offer in ways an old appraisal cannot capture.

This is why a thoughtful buyer values your item independently rather than simply reading a figure off your paperwork.

How Gold and Diamonds Are Actually Valued for Sale

Gold jewellery and coins

Gold is valued by purity and weight. Purity is expressed in carats, with higher-carat gold such as 18-carat containing more pure gold than 14-carat, and therefore carrying more value per gram. The item is weighed, the purity is confirmed by testing, and the gold content is priced against the live international gold price on the day. Krugerrands and other gold coins are valued similarly, with their bullion content measured against the current market.

Diamonds

Diamonds are assessed on the four Cs: cut, colour, clarity and carat weight. A grading report from a recognised gemological laboratory adds confidence by independently confirming these characteristics. Larger, cleaner, better-cut stones command stronger offers, but condition and current demand still play a role in what a buyer will pay.

Luxury watches

Watches are a category of their own. Brand, model, reference, condition, service history and the presence of original box and papers all influence value, alongside current collector demand for that specific piece.

What You Actually Need When You Want to Sell

An insurance appraisal is useful background, but it is not the tool for selling. What you need is a current, transparent valuation from a buyer who explains exactly how the offer is reached. A trustworthy valuation should show you:

1. The weight and tested purity of your gold, or the grading details of your diamond.
2. The live market price being used on the day.
3. How condition affects the figure.
4. A clear, no-pressure offer you are free to accept or decline.

If a buyer cannot or will not walk you through these points, that is a reason to look elsewhere.

Frequently Asked Questions

Will you pay me the value on my insurance appraisal?

No, and no honest buyer will. An insurance appraisal states retail replacement cost for a new item, which includes store markup and overheads that cannot be recovered on resale. Our offer reflects the real, current resale value based on weight, purity, condition and the live market.

Do I need an appraisal before I bring my jewellery in?

You do not need one. We carry out our own valuation at our Illovo premises, weighing and testing your items in front of you and pricing them against the live market on the day. Any paperwork or grading reports you already have are welcome, but they are not required.

How is the value of my gold worked out?

Your gold is weighed and tested to confirm its purity in carats, then the pure gold content is priced against the live international gold price for that day. Higher-purity gold carries more value per gram.

Do you buy items without diamond grading certificates?

Yes. A certificate from a recognised laboratory adds confidence and can support a stronger offer, but our team can assess your diamond on the four Cs in person if you do not have one.
