Key takeaway: A gold exchange buys gold, coins, diamonds and watches from the public and pays you for them on the day. Searching for one near you in Johannesburg returns pawn shops, scrap counters and bullion sellers alongside genuine buyers, and they are not the same trade. What separates them is a fixed office you can find, registrations you can verify, testing you can watch, and payment at the table. The Gold Avenue is a specialist buyer on the 8th floor of Illovo Point in Illovo, Sandton.
This guide is for someone in Johannesburg with gold to sell and no idea who to trust with it. It covers what a gold exchange actually is, what happens from the moment you walk in, what your items are measured on, what the offer is built from, and the signals that tell you to leave. It is written from the buying side of the desk at The Gold Avenue.
What a gold exchange is, and what it is not
The phrase gets used loosely. Several different businesses advertise under it in Johannesburg, and only one of them is set up to buy your ring outright and pay you for it today.
The types of gold buyer, and who buys from the public
A specialist buyer does this as the whole business, not as a sideline.
| Business | What it does | What that means for you |
|---|---|---|
| Specialist buyer | Buys gold, coins, diamonds and watches from the public as its core trade | Sell outright, paid the same day |
| Pawn shop | Lends against the item and sells what is not redeemed | You get the item back only if you repay |
| Jeweller | Makes and sells; some buy from the public as a sideline | Better for a remake or a reset than a sale |
| Refiner | Melts and refines for the trade | Generally will not deal with a private seller |
| Bullion seller | Sells new coins and bars | The wrong direction if you are selling |
Everything at a specialist buyer, from the testing equipment to the payment systems, is built around buying rather than selling. Our article on choosing a gold dealer near you goes further into separating them.
Where to find The Gold Avenue in Johannesburg
We are at Office 804 on the 8th floor of Illovo Point, 68 Melville Road, Illovo, Sandton, 2196, a few minutes from Sandton CBD.
Illovo Point is an AAA-grade office building with boom-controlled access, underground parking, 24/7 CCTV, 24-hour guarding and tactical response in the area. Valuations happen in a private, air-conditioned booth rather than at an open counter, which matters when you are carrying something valuable. Booked clients are sent step-by-step photo directions covering the entrance, the parking and the lift, so nobody arrives lost. More is on our safety page.
Clients travel in from Sandton, Rosebank, Hyde Park, Melrose Arch, Parktown North, Bryanston, Morningside, Fourways, Randburg and Houghton, and from Midrand, Centurion and Pretoria when the collection justifies it. From the south or east of Johannesburg a secure courier is frequently the better answer than the drive, and we arrange one. Home and office appraisals are also available.
What you can exchange
| Category | What is taken | What is looked at |
|---|---|---|
| Gold jewellery | 9ct to 24ct, hallmarked or not, broken, damaged, tarnished, designer or unworn | Weight and purity, which give the fine gold content |
| Krugerrands and coins | Krugerrands in every size, Proteas, Naturas, SA Ponds, Sovereigns, Britannias, Maple Leafs, Gold Eagles | Fine gold content and what the trade pays that day |
| Diamonds | Certified and non-certified, loose or set in rings, earrings, tennis bracelets and necklaces | Carat, colour, clarity, cut, certification, marketability |
| Luxury watches | Rolex, Patek Philippe, Audemars Piguet, Omega, TAG Heuer, Breitling, Cartier, IWC, Panerai | Brand, model, year, condition, demand, box and papers |
| Gold bars | Minted and stamped bars, and gold collector pieces | Weight, purity and verification |
The full list is on what we buy. Not everything qualifies, and knowing that before you drive anywhere is worth more than a polite meeting: gold coins only, so commemorative and collector coins struck in base metal are out whatever the packaging says; gold plated and gold filled items hold almost no recoverable gold and are identified in seconds; costume jewellery with no precious metal content is not bought; and nothing is bought without ID, because every transaction runs under FICA. If you are unsure, send a photo on WhatsApp to 076 393 5429 first.
What happens on the visit
At a properly run exchange the sequence is the same every time, and it is short.
A visit to a gold exchange, arrival to payment
At The Gold Avenue this typically runs 10 to 15 minutes.
- You arrive. Walk in or book ahead by phone, WhatsApp, email or through the website. You are taken to a private, air-conditioned booth and offered refreshments.
- Your items are tested in front of you. Weighed, then read with a Niton XRF gold analyser. Diamonds go through the Sherlock Holmes-Yehuda laboratory system and professional testers, watches through specialist authentication tools. Nothing leaves the desk.
- You get an offer, and the reason for it. Explained item by item. You can say no and leave with everything you brought in.
- If you accept, the paperwork is done at the desk. Details captured on an iPad, a one-page Sale Agreement signed electronically.
- You are paid. Immediate EFT with immediate clearance across participating South African banks. Cash is subject to ID, compliance and the cash held on the premises, and larger amounts need a few business days’ notice.
Returning clients are frequently finished in under five minutes.
How the offer is worked out
Nothing about it is a guess, and nobody should ask you to accept a number without an explanation. Gold jewellery runs through the same sequence every time.
From weight to offer
Coins, diamonds and watches follow their own routes, priced on their own merits.
Purity is the part sellers underestimate. Two chains of identical weight can be worth very different amounts, because only part of each gram is gold and a buyer pays for that part.
Fine gold content by carat
A 9ct chain holds well under half the gold of a 24ct piece of the same weight.
| Marking | Stamp | Fine gold | Where you tend to see it |
|---|---|---|---|
| 9ct | 375 | 37.5 percent | Widespread in older South African jewellery |
| 14ct | 585 | 58.5 percent | Imported and designer pieces |
| 18ct | 750 | 75 percent | Fine jewellery and most diamond settings |
| 22ct | 916 | 91.6 percent | Indian and Middle Eastern jewellery, and Krugerrands |
| 24ct | 999 | 99.9 percent | Bars, wafers and investment pieces |
An unmarked piece is no obstacle, because the analyser reads the metal itself. Beyond weight and purity, a few things move the number: solder and fittings are frequently a lower purity than the piece they sit on; stones are assessed separately where they carry resale value; condition does not change gold content, so do not polish, repair or break anything up first, though it matters on watches and designer pieces; and branded pieces with resale value above their metal are valued on that instead. Our guide on how to check if gold is real covers what you can tell at home.
Why an offer sits below a retail price or an insurance valuation
This is the single most common surprise, and it is better understood before you come in than after.
What is inside a retail price
A buyer pays on the underlying value, not on what it cost to sell the piece to you new.
An insurance valuation is a replacement figure. A retail price carries manufacturing, design, branding, retail mark-up and VAT. None of that comes back on resale, so no honest buyer anywhere pays against those numbers. Our guide to what gold jewellery is worth goes further into that gap, and understanding jewellery appraisals explains what a valuation document is actually for.
Krugerrands and gold coins
Coins are not weighed in as scrap. Pricing follows the live gold price, the rand and what trade buyers are paying that day, which is why no honest exchange publishes a fixed coin price.
| Size | Fine gold content | Gross weight |
|---|---|---|
| 1oz | 31.10 g | 33.93 g |
| Half ounce | 15.55 g | 16.97 g |
| Quarter ounce | 7.78 g | 8.48 g |
| Tenth ounce | 3.11 g | 3.39 g |
Look at the gap between those columns. A Krugerrand is 22ct, but the copper is added on top of a full troy ounce of fine gold rather than taken out of it, so a 1oz coin carries a full ounce and weighs more than an ounce. Applying 91.6 percent to the gross weight understates the coin. The same care applies to the other gold coins bought, and the background is in the history of Krugerrands.
What gold has done in rands
The reason nobody can quote you a price over the phone and hold it is that the underlying number moves daily, in two currencies at once.
Gold price in rand per troy ounce, annual average, 1999 to 2026
Market gold price, not an offer.
| Year | Gold, USD per ounce | USD/ZAR | Gold, rand per ounce |
|---|---|---|---|
| 1999 | $279 | 6.12 | R1,706 |
| 2008 | $872 | 8.27 | R7,163 |
| 2016 | $1,250 | 14.69 | R18,330 |
| 2020 | $1,771 | 16.44 | R29,149 |
| 2024 | $2,389 | 18.32 | R43,679 |
| 2026 | $4,560 | 16.37 | R74,606 |
Two engines drive that line: the dollar gold price and the rand exchange rate. They do not always pull together, which is why the rand gold price has climbed in years when the dollar price fell. Those are market prices for the metal, from the LBMA gold price and the European Central Bank rand rate, and they are not what any buyer pays you, because refining costs and a commercial margin come off first. An exchange advertising a fixed rate per gram is either behind the market or building the gap into its margin. Day to day detail is in the Krugerrand price today in rands.
How diamonds and watches are priced
Diamonds are not priced off a scale the way gold is. Each stone is assessed on carat, colour, clarity and cut together, not carat alone, then on certification and on what it will actually resell for, referenced against the Rapaport Diamond Report. GIA-certified stones are straightforward; non-certified stones are considered subject to due diligence on origin.
A watch is priced on what the secondary market will pay for that exact reference in that exact condition, which has little to do with its original retail price. Brand, model, year, condition and demand all feed in. Box, papers and the warranty card are ideal; without them an invoice or service history helps, and a sale is still possible after authentication.

Red flags at a gold exchange
- Your items go out of sight. Whatever the reason given, testing happens in front of you or not at all.
- No ID is asked for. Every transaction runs under FICA. A buyer who skips it is not following the law.
- A rate advertised as fixed. It cannot be fixed.
- Pressure to decide on the spot. A valuation carries no obligation. If leaving feels difficult, leave.
- No fixed address. A phone number and a meeting point is not a business.
- An offer quoted before anything is weighed. There is nothing to base it on yet.
Ask directly about the second-hand goods dealer certificate under the Second-Hand Goods Act and registration with the Financial Intelligence Centre. The Gold Avenue holds both, has been a member of the Jewellery Council of South Africa since 2023, sits on the Second-Hand Dealers and Pawn Board, and is a registered credit provider with the National Credit Regulator. More checks are in our article on avoiding scams when selling gold.
What to bring
| Bring | Why | Required |
|---|---|---|
| SA ID, passport or SA driver’s licence | Identity verification under FICA | Yes, at any registered dealer |
| Proof of banking details | Payment goes to an account in your name | Yes, for EFT |
| The items exactly as they are | Do not polish, repair or break anything up first | Yes |
| Certificates, box and papers | Diamond certification and watch paperwork support the offer | No, helpful when you have them |
Frequently asked questions
Is there a gold exchange near me open now in Johannesburg?
The Gold Avenue is open Monday to Thursday 08:00 to 17:00 and Friday 08:00 to 16:00. Saturday is by pre-booked appointment only, and we are closed on Sundays and public holidays.
Which gold exchange pays the most?
Compare buyers on how they test, whether you can watch, what they pay on, and how fast the money moves, rather than on a rate advertised online. An advertised rate is not what you are paid once deductions are applied.
Do gold exchanges pay cash?
The Gold Avenue pays by immediate EFT with immediate clearance across participating South African banks. Cash is possible subject to ID, compliance and the cash held on the premises, and larger amounts need a few business days’ notice.
Will a gold exchange buy broken or unmarked gold?
Yes. Condition does not change the gold content and a missing hallmark is not a problem, because the XRF analyser reads the real composition. Gold plated and gold filled items are a different matter and are identified in seconds.
Can I get my item back after selling it?
At The Gold Avenue, through a Buyback Agreement. The exchange buys the item and pays you, and you may repurchase it on an agreed date at a price set up front. It covers Krugerrands, gold and diamond jewellery, luxury watches and high-grade polished diamonds.
Do I need an appointment?
Not at The Gold Avenue. Walk-ins are welcome during opening hours, and booking guarantees a private booth is free when you arrive and triggers photo directions for the building.
Can you collect, or come to me?
Yes. Secure couriers are arranged, and appraisals are carried out at your home or office, which suits larger collections and anyone who would rather not travel with valuables.
Will you buy diamonds without a certificate?
Yes. Certified and non-certified diamonds are both considered, with non-certified stones subject to due diligence on origin.
