Spring cleaning season has arrived across many South African homes this October, and with it comes a steady stream of sellers walking into The Gold Avenue, the Illovo, Sandton buyer of gold, diamonds, luxury watches and Krugerrands. The firm says most of these visitors turn up holding a jumble of pieces spanning different eras, countries and jewellers, rarely aware that two chains of matching weight can fetch wildly different sums. To clear up the confusion, the company is explaining one of the single biggest drivers of any gold jewellery offer: the carat of each item.
Jewellery is hardly ever made of pure gold. It is an alloy, blending gold with other metals to add strength and shift its colour. Carat reveals the proportion of the piece that is genuinely gold, and it is that fine gold content, not the piece’s total weight, on which any gold offer rests.
What carat actually means
Carat expresses gold content in parts out of 24. Gold at 24 carat sits close to pure. An 18 carat item is 18 parts gold out of 24, equal to 75 percent gold. A 14 carat item runs to roughly 58.5 percent gold, while 9 carat comes in at 37.5 percent gold. Twenty two carat gold, common in some traditional jewellery, works out to around 91.7 percent gold.
So a 9 carat bracelet and an 18 carat bracelet weighing exactly the same hold very different quantities of gold. Twice as much fine gold sits inside the 18 carat piece as in the 9 carat one. Whenever sellers wonder why one item paid out more than another of similar size, carat is usually the answer.
Why a jewellery box rarely has one value
Hardly anyone who sets out to Sell Gold Jewellery shows up with just one item. They bring a hoard assembled across the years: a wedding band, a chain passed down from a grandparent, earrings picked up on holiday, a bracelet that snapped and never made it to repair. Those pieces can each be a different carat. A few may be hallmarked and others not. Some may turn out to be gold plated instead of solid gold.
That is precisely why The Gold Avenue grades every piece on its own. Tossing the whole lot onto one scale and applying a single carat across it can short-change the seller, since the higher carat pieces get dragged down by the lower carat ones. Grading each item separately means every piece is paid for exactly what it holds.
Hallmarks help, but they are not the whole story
Plenty of pieces bear a stamp like 9ct, 375, 18ct or 750 to signal the carat. Handy as a hallmark is, it does not settle the matter by itself. Stamps rub away over time, older or imported pieces can be marked under different conventions, and plenty of items carry no stamp whatsoever. The Gold Avenue purchases gold from 9 carat right through to 24 carat, hallmarked or not, and leans on testing rather than the stamp to verify content.
How the carat is confirmed in front of the seller
The firm relies on a Niton XRF analyser, an X ray device that scans a piece and reads its carat content without leaving a mark or causing any damage. Every item is then placed on a gold scale while the seller watches. Both the carat reading and the weight underpinning the offer are visible to the seller, keeping the valuation fully transparent from start to finish.
That counts for a lot with pieces a seller is uncertain about. Items that pass for solid gold yet are only plated, or pieces of murky origin, get picked out during the free valuation. Nobody pays to discover what they are holding, and there is never any pressure to sell.
What else shapes the offer
With the fine gold content established, the offer is weighed against the live gold price and the rand on the day, alongside prevailing trade rates, and the refining cost is factored in. Since both the gold price and the exchange rate shift from one moment to the next, an offer mirrors the market at the point of sale, not some figure quoted days before.
Pieces holding diamonds are valued apart from the gold surrounding them. The Gold Avenue buys GIA certified and non certified diamonds and diamond jewellery, taking in rings, engagement rings, necklaces and chains. Designer or branded pieces can likewise be valued on a different basis from plain gold, and sellers are urged to flag any brand, box or receipt still in their possession.
Experienced Jewellery Buyers in a secure setting
Operating as Jewellery Buyers out of a private office rather than behind a shop counter, The Gold Avenue values each piece inside a private booth on the 8th floor of Illovo Point, a AAA grade building fitted with boom controlled access, underground parking, 24 hour guarding and 24/7 CCTV. Gold jewellery of every kind and in any condition is welcome, from rings, earrings, necklaces and chains to brooches and bracelets, in yellow, white and rose gold, and platinum too.
A phone call, a WhatsApp, an online chat or a booking all work, and walk-ins are welcome through business hours. Anyone who would rather stay put can set up a home or office appraisal anywhere in Gauteng, and secure couriers can be arranged for sellers based further afield.
Cash for Jewellery, paid on the day
The moment a seller agrees to an offer for Cash for Jewellery, their details go onto an iPad and a single page Sale Agreement is signed electronically. Every transaction meets FICA, so a South African ID, passport or South African driver’s licence plus proof of banking details are required. Payment lands by immediate EFT with immediate clearance at participating South African banks, or in cash subject to identification, compliance and the cash on hand at the premises. Bigger cash sums call for a few business days’ notice.
A standard visit runs ten to fifteen minutes. The Gold Avenue has looked after more than 3,000 clients since it opened in April 2022 and carries a 5.0 rating on Google.
Advice for spring sellers
For anyone going through their jewellery this month, the firm keeps its tips grounded. Store pieces apart instead of knotting them together in a single bag. Resist the urge to clean or polish anything ahead of a valuation. Carry along any certificates, receipts or boxes. And insist that any buyer display the carat reading and the weight for each piece, so the offer makes sense item by item.
