Key takeaway: Jewellery buyers fall into five types: pawn shops, jewellers, online marketplaces, auction houses and specialist buyers, and each one is set up for a different kind of sale. The Gold Avenue in Illovo, Sandton is a specialist buyer that values the metal, the stones and the piece itself in front of you, pays immediately, and can place the right items with its international network.
A pawn counter, a jeweller, an auction house and a gold buyer all say they “buy jewellery”, yet the same ring can attract very different offers from each. This guide explains what each type of buyer is set up to do, when a piece is worth more than its metal, and how The Gold Avenue handles the difference.
Types of jewellery buyers and what each one pays for
| Buyer type | What they pay for | Speed | Suits |
|---|---|---|---|
| Pawn shop | A loan against the item, which you repay to get it back | Same day | Someone who wants the item back |
| Jeweller or trade-in | A trade-in or credit against a new purchase | Varies | Upgrading or remodelling |
| Online marketplace | Whatever a private buyer offers | When a buyer is found | Patient sellers with branded pieces and paperwork |
| Auction house | Hammer price less the auction house’s commission | After the sale date | Rare signed pieces |
| Specialist buyer | Metal, stones and resale demand, paid immediately | Minutes | Gold, diamond and designer jewellery, and watches |
Pawn shops
A pawn shop is a lender first. It advances money against your jewellery and holds the piece until you repay the loan. Pawning makes sense only if you want the item back. If you are ready to part with the piece, an outright sale is the simpler route.

Jewellers and antique jewellery shops in Johannesburg
A retail jeweller’s business is selling new pieces, so when it buys jewellery it is often as a trade-in or as credit towards something in the cabinet rather than cash. That is a good deal if you were going to buy from them anyway. It is a poor one if you wanted money.
An antique jewellery shop buys to resell to collectors, so it is interested in the pieces its own customers are looking for. If you have a piece you believe is antique, an antique dealer is worth a visit, but treat its offer as one data point rather than the answer.
Auction houses and online marketplaces
An auction house sells on your behalf for a commission, on its own timetable, and there is no guarantee the piece sells at all. It is a route for pieces of genuine rarity and for sellers who can wait.
Online marketplaces put you in front of private buyers, which can work for a branded watch or a designer piece with full paperwork. The downside is that you are meeting strangers while carrying valuables and handling payment yourself.
Specialist gold, diamond and jewellery buyers
A specialist buyer does one thing: assess and buy jewellery, coins, diamonds and watches from the public, then place them where they are worth most, whether that is a refinery, the diamond trade, the watch trade or an overseas buyer in its international network. Because it has more than one outlet, it can pay on more than the metal.
At The Gold Avenue every piece is assessed in three layers. The metal is weighed and read on a Niton XRF analyser for exact purity. Any stones are graded on carat, colour, clarity and cut, tested on the Sherlock Holmes-Yehuda laboratory diamond system and referenced against the Rapaport Diamond Report and what trade dealers will pay. GIA-certified and non-certified stones are both considered, with non-certified stones subject to due diligence on origin, and loose stones are bought as well as set ones.
Then the piece itself is considered: whether it is a designer piece worth more than its metal, and whether it is something the international network would pay more for. The offer reflects all three layers, and it is explained to you. The metal method is set out on the gold jewellery page and the stone method on the diamond jewellery page.
Antique and vintage jewellery: when a piece is worth more than its gold
Most inherited jewellery is worth its metal and stones, and a smaller share is worth more. A recognised designer name, a piece in original condition, or a piece with its original box and papers can lift the offer above melt value, because there is a market for the finished piece rather than for the gold in it.
Age alone does not add value. A plain 9ct chain from decades ago is a plain 9ct chain. Where a piece does qualify, The Gold Avenue can export the right jewellery, watches and polished diamonds through its international network to overseas buyers who often pay more than local dealers, and that possibility is priced into the offer.
A written appraisal from a jeweller can help you understand what you have before you sell. Our guide to understanding jewellery appraisals explains what those documents do and do not tell you.
Frequently asked questions
Who pays the most for jewellery?
For ordinary gold and diamond pieces, a specialist buyer that pays for the metal and the stones and can resell through more than one channel. For a rare signed piece, the buyer that can reach collectors, whether through an auction or an international network. Ask each buyer what it is paying for, not just how much.
Do antique jewellery buyers pay more than gold buyers?
Only for pieces their customers want. A specialist buyer that values the metal, the stones and the piece itself covers both cases in one visit.
Are diamond buyers and jewellery buyers the same thing?
Not always. Some jewellery buyers only price metal. A buyer with diamond testing equipment and access to the diamond trade prices the stone separately, which is what you want for any ring, bracelet or pair of earrings with a real diamond in it.
Do I need an appraisal before I sell my jewellery?
No. An appraisal is useful background, but it is written for insurance and reflects replacement cost, which is much higher than second-hand value. A buyer will assess the piece itself. Bring the appraisal if you have one, along with any certificates, box or papers.
