A broken necklace, an inherited ring or a small collection of gold coins can have value, but the amount a buyer offers depends on more than the current gold price. Understanding how gold is assessed helps you recognise a fair process and avoid accepting an offer you do not understand.
This gold buyers blog explains the practical details behind selling gold in Australia, including purity, weighing, jewellery resale value and the questions worth asking before completing a transaction.

How Do Gold Buyers Calculate an Offer?
Gold buyers generally assess an item’s metal content, weight and potential resale or refining value. The final offer may also reflect the type of item, market conditions and the buyer’s operating costs.
For jewellery sold primarily for its metal, the basic calculation starts with the amount of pure gold it contains. A 20-gram necklace made from 18-carat gold, for example, contains approximately 15 grams of pure gold before considering any non-gold components. That does not mean the seller will receive the full market value of those 15 grams. The buyer must still account for the actual item, its condition and the terms of the transaction.
Purity, Weight and Hallmarks
Gold purity is expressed in carats or fineness. Carats describe the proportion of gold in an alloy, while fineness expresses that proportion in parts per thousand.
| Marking | Common Description | Approximate Gold Content |
|---|---|---|
| 375 | 9 carat | 37.5% |
| 585 | 14 carat | 58.5% |
| 750 | 18 carat | 75% |
| 916 | 22 carat | 91.6% |
| 999 | Fine gold | 99.9% |
A hallmark can provide useful information, but it does not prove authenticity by itself. Professional testing may be needed if a marking is missing, unclear or inconsistent with the item.
Gold is commonly weighed in grams during jewellery valuations. Bullion markets also use troy ounces, with one troy ounce equal to approximately 31.1035 grams. Ask whether the displayed weight includes gemstones, non-gold fittings or other materials that may not be included in the metal valuation.
Does the Spot Gold Price Equal the Selling Price?
No. The spot price is a benchmark for the market value of gold, not a guaranteed amount paid to someone selling jewellery or bullion.
A buyer’s offer may differ because of purity, refining requirements, resale potential, dealer costs and applicable premiums or discounts. A gold coin with recognised bullion value may be assessed differently from a damaged bracelet of the same gold weight.
When comparing offers, ask for the purity assessment, the weight used in the calculation and the amount offered. If deductions apply, request an explanation. A clear breakdown makes it easier to compare two valuations than a single headline figure.
What Types of Gold Can Be Sold?
Many buyers consider a range of gold items, although accepted categories and valuation methods vary between businesses.
Broken and Unwanted Jewellery
Broken chains, single earrings and damaged rings may still have metal value. If an item is being purchased for refining, its condition may matter less than its gold content. However, gemstones, craftsmanship and collectability can change the appropriate selling method.
A designer piece or antique ring may be worth more as jewellery than as scrap metal. Before selling an unusual or valuable item for its gold content, consider whether a specialist jewellery appraisal would provide a better understanding of its resale potential.
Bullion, Coins and Gold Bars
Bullion is generally valued with close attention to its gold content, weight, authenticity and market demand. Recognised coins and bars may also carry premiums related to their format, condition or resale market.
Keep original packaging, certificates and purchase records where available. These do not replace authentication, but they may help a buyer assess the item. Avoid cleaning collectible coins, as cleaning can damage their surfaces and potentially affect their value.
Using a Gold Buyers Blog to Prepare for a Valuation
Research is most useful when it helps you ask specific questions rather than simply comparing advertised prices. A gold buyers blog can provide context about gold buying services in Melbourne, including the factors that influence how unwanted gold is assessed. The same principles can help sellers across Australia prepare for a more informed transaction.
Before visiting a buyer, separate your items by type and note any visible purity markings. Photograph valuable pieces and record their approximate weights if you have suitable scales. Home measurements are only a reference; professional equipment and testing should determine the assessment.
For inherited or unfamiliar jewellery, gather any available receipts, certificates or previous appraisals. If a piece has sentimental value, decide in advance whether you are comfortable selling it. Once ownership has transferred, recovering the item may not be possible.
Local Gold Buyers Versus Mail-In Services
A local gold buyer offers the opportunity to discuss the assessment in person. You may be able to observe weighing, ask questions and decline an offer before leaving. This can be useful for sellers who want immediate clarification or have several different items.
Mail-in services can be convenient for Sydney gold buyers who cannot easily visit a physical location. However, sellers should understand the postage arrangements, insurance coverage, testing process, return policy and what happens if they reject the offer. Check who is responsible for the item at each stage.
Neither option is automatically better. The right choice depends on the value of the items, the transparency of the process, convenience and your comfort with the transaction.
Questions to Ask Before Accepting an Offer
A transparent valuation should leave you with a clear understanding of what is being purchased and how the amount was determined. Before agreeing to sell, consider asking:
- What purity and weight have been used to calculate the offer?
- Is the item being valued for its metal content or potential resale?
- Are any fees or deductions included in the quoted amount?
- Can I decline the offer without an obligation to sell?
- What identification or documentation does the business require?
- When and how will payment be made?
- Will I receive a receipt describing the items and transaction?
For high-value jewellery, bullion or an estate collection, obtaining more than one valuation can be worthwhile. Compare the actual terms rather than assuming the highest advertised rate will produce the highest final offer.
Keep valuable items secure while travelling and avoid leaving them unattended. If a buyer needs to retain an item for further testing, request written documentation explaining the arrangement. A careful selling decision is one based on a clear valuation, understood terms and enough time to consider the offer.
