The Gold Avenue Guide to How Carat Defines a Gold Piece
Why does one gold chain fetch more than another of the exact same weight? For many South Africans clearing out their jewellery this spring, the answer comes down to a single word: carat. The Gold Avenue, the Illovo, Sandton buyer of gold, diamonds, luxury watches and Krugerrands, is helping sellers get to grips with this, one of the biggest influences on what a piece is worth. As October spring cleaning gets going in homes around the country, the company reports that many of the people it sees arrive with a jumble of items spanning different decades, different countries and different jewellers, rarely aware that weight alone tells only half the story.
Jewellery is hardly ever made from pure gold. It is an alloy, gold blended with other metals to add strength and vary the colour. Carat reveals how much of any given piece is genuinely gold, and it is that fine gold content, not the total weight, on which an offer rests.
What carat actually means
Carat expresses gold content as parts out of 24. Gold at 24 carat sits close to pure. At 18 carat, a piece is 18 of 24 parts gold, which works out to 75 percent. A 14 carat item runs to roughly 58.5 percent gold, while 9 carat comes in at 37.5 percent. Twenty two carat gold, common in some traditional jewellery, is around 91.7 percent gold.
So a 9 carat bracelet and an 18 carat bracelet weighing the same contain markedly different quantities of gold. The 18 carat version carries twice the fine gold of its 9 carat counterpart. Where sellers notice they were paid more for one item than another, carat is frequently the reason behind the gap.
Why a jewellery box rarely has one value
Few people who choose to Sell Gold Jewellery turn up with just one piece. They bring a collection assembled over the years: a wedding band, a chain passed down from a grandparent, earrings picked up abroad, a bracelet that snapped and was never mended. Any of these might be a different carat. One or two may be hallmarked and others not. Some could turn out to be gold plated instead of solid gold.
That is exactly why The Gold Avenue examines each piece on its own. Tipping everything onto a single scale and applying one carat across the board can short change the seller, since the higher carat items get dragged down by the lower ones. Assessing pieces separately means each is paid according to what it genuinely holds.
Hallmarks help, but they are not the whole story
Plenty of pieces bear a stamp such as 9ct, 375, 18ct or 750 pointing to the carat. A hallmark is handy, yet on its own it proves nothing. Stamps rub away over time, older and overseas pieces may follow different marking conventions, and some items bear no mark whatsoever. The Gold Avenue buys gold ranging from 9 carat to 24 carat, hallmarked or not, and trusts testing rather than the stamp to verify content.
How the carat is confirmed in front of the seller
To do this, the company relies on a Niton XRF analyser, an X ray device that scans a piece and reports its carat content without leaving a mark or causing damage. Each item is then placed on a gold scale while the seller watches. The seller takes in both the carat reading and the weight underpinning the offer, keeping the valuation fully transparent from start to finish.
This counts for a great deal with pieces sellers are uncertain about. Anything that resembles solid gold but turns out to be plated, or an item of unclear origin, is flagged during the free valuation. Nobody is charged simply to learn 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 measured against the live gold price and the rand on the day, alongside prevailing trade prices, with refining costs also factored in. Since both the gold price and the exchange rate shift continuously, an offer mirrors the market at the moment of sale rather than some figure quoted a few days before.
Items set with diamonds are valued apart from the gold holding them. The Gold Avenue buys GIA certified and non certified diamonds and diamond jewellery, including rings, engagement rings, necklaces and chains. Designer and branded pieces might also be treated differently from plain gold, so sellers are urged to flag any brand, box or receipt they have held onto.
Experienced Jewellery Buyers in a secure setting
Operating as Jewellery Buyers based in a private office rather than behind a shop counter, The Gold Avenue values every piece in a private booth on the 8th floor of Illovo Point, a AAA grade building offering boom controlled access, underground parking, 24 hour guarding and 24/7 CCTV. The company takes all types of gold jewellery in any condition, from rings, earrings, necklaces and chains to brooches and bracelets, across yellow, white and rose gold, and platinum too.
Sellers are free to call, drop a WhatsApp, chat online or book a slot, and walk-ins are welcome within 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 out.
Cash for Jewellery, paid on the day
When a seller agrees to an offer for Cash for Jewellery, their details are logged on an iPad and a single page Sale Agreement is signed electronically. Every transaction complies with FICA, so a South African ID, passport or South African driver's licence plus proof of banking details are required. Payment comes through immediate EFT that clears straight away across participating South African banks, or in cash subject to identification, compliance and the cash on hand at the premises. Sizeable cash sums call for a few business days' notice.
A standard visit runs about ten to fifteen minutes. Since it opened in April 2022, The Gold Avenue has looked after more than 3,000 clients and carries a 5.0 rating on Google.
Advice for spring sellers
The company's tips for anyone going through their jewellery this month are down to earth. Keep pieces apart instead of bundled together in one bag. Resist cleaning or polishing anything ahead of a valuation. Bring along any certificates, receipts or boxes. And ask whichever buyer you use to display the carat reading and the weight for each piece, so the offer makes sense item by item.
