Key takeaway: Your gold jewellery is worth something if it is real gold rather than plated. Check for a hallmark such as 9ct, 18ct or 750, confirm the metal with a proper test, then weigh it. Value comes from purity and weight measured against the live gold price.

It is one of the most common questions we hear at our counter in Illovo. Someone inherits a box of jewellery, clears out a drawer, or decides a dated piece is never going back on, and they want to know whether any of it actually has value. The honest answer is that some gold jewellery is worth a meaningful amount and some is worth very little, and the difference usually comes down to a few things you can check yourself before you ever speak to a buyer.

This guide walks you through how to tell whether your gold jewellery is worth anything, how dealers in Johannesburg work out a figure, and what separates a fair offer from a poor one. It is written by a buyer who tests and pays for gold every working day, so the focus is on what genuinely moves the number rather than vague advice.

First, Is It Actually Gold?

The single biggest factor in whether your jewellery is worth anything is whether it is solid gold or merely gold plated. Plated pieces have a thin layer of gold over a base metal such as brass or copper. They can look identical to the real thing, but for resale purposes they hold almost no intrinsic value, because there is so little gold present.

Before you get your hopes up or write a piece off, look for the clues that tell you what you are holding.

Look for a hallmark

Most genuine gold jewellery carries a small stamp, usually on the inside of a ring band, the clasp of a chain, or the post of an earring. In South Africa and the United Kingdom you will commonly see marks such as:

• 9ct or 375, meaning 9 carat, or 37.5 percent pure gold.
• 14ct or 585, meaning 14 carat, or 58.5 percent pure gold.
• 18ct or 750, meaning 18 carat, or 75 percent pure gold.
• 22ct or 916, common in jewellery of Indian or Middle Eastern origin.
• 24ct or 999, which is effectively pure gold and rare in everyday jewellery because it is too soft.

The carat number tells you how many parts out of 24 are pure gold. The three digit number is the same information written as a fineness, so 750 means 750 parts per thousand. Both describe the proportion of pure gold mixed with harder alloy metals that give the piece strength.

Watch for plating stamps

Marks like GP (gold plated), GF (gold filled), RGP (rolled gold plate) or HGE tell you the piece is not solid gold. A ring that says 18K GP is plated, not 18 carat throughout. If you see one of these, the item is almost certainly worth little as scrap, however attractive it looks.

When there is no mark at all

An absent hallmark does not automatically mean the piece is worthless. Older items, handmade pieces and jewellery that has been resized can lose their stamp. It simply means you cannot rely on the marking alone and the metal needs to be tested properly.

Simple Checks You Can Do at Home

None of these is conclusive on its own, but together they help you decide whether a piece is worth taking to a buyer.

• The magnet test. Gold is not magnetic. If a strong magnet pulls your piece firmly, the core is likely a base metal. Passing this test does not prove gold, but failing it is a strong warning sign.
• Look for wear. On plated jewellery, the gold layer rubs away over time, often around edges and high points, revealing a different colour underneath. Solid gold wears evenly and keeps its colour right through.
• Check for discolouration. Green or black marks on your skin, or tarnish on the metal, point to base metal or low purity rather than solid gold.

Avoid the scratch and acid tests you might read about online. Done incorrectly they damage your jewellery, and a professional acid or electronic test at a reputable buyer is free, accurate and non destructive on the parts that matter.

How Dealers Work Out What Your Gold Is Worth

Once a piece is confirmed as solid gold, the calculation is more straightforward than most people expect. The value of gold jewellery sold for its metal rests on two numbers.

1. Purity. A 9ct piece contains far less pure gold than an 18ct piece of the same weight, so it is worth proportionally less per gram.
2. Weight. Gold is weighed in grams. Heavier pieces simply contain more gold.

A buyer multiplies the pure gold content by the live gold spot price, which moves throughout every trading day. This is why no honest dealer can quote you an exact figure over the phone without weighing and testing the piece first, and why two valuations taken weeks apart can differ purely because the market shifted.

Stones, branding and craftsmanship can add value on top of the metal for certain pieces, particularly signed designer jewellery or items with significant diamonds. For most everyday gold, though, the metal weight is what drives the offer. If you have diamond jewellery, that is assessed separately on the quality of the stones as well as the setting.

What Lowers the Value, and What Does Not

A few myths cost sellers money, so it is worth being clear.

• Damage and tangling do not matter much. A broken clasp, a snapped chain or a single earring still holds its full gold value. You do not need to repair anything before selling for scrap.
• Old fashioned styling does not reduce metal value. Gold is gold regardless of whether the design is in fashion.
• Mixed lots are fine. You can bring a drawer of odd pieces in different carats. A good buyer sorts and weighs them by purity.
• What does reduce value is non gold content. Clasps, spring mechanisms and the base under plating are not gold and are not paid for.

Why Where You Sell Changes the Number

Two sellers with identical jewellery can walk away with very different amounts depending on who they deal with. Pawnbrokers and some high street gold buyers build a wide margin into their offers, banking on the fact that most people do not know what their gold actually contains.

At The Gold Avenue we built our business around the opposite approach. We weigh and test your pieces in front of you, explain the purity and the live price we are working from, and make an offer you can see the logic behind. Because we work an international dealer network, particularly in the UAE, we are able to pay local Johannesburg sellers more competitively than the traditional pawn and gold buying trade. There is no obligation to accept, and nothing is hidden.

Frequently Asked Questions

How do I tell if my gold jewellery is real or plated?

Start by looking for a hallmark such as 9ct, 18ct or 750, which indicates solid gold. Marks like GP, GF or RGP indicate plating. A magnet that pulls the piece, or wear that reveals a different colour underneath, points to base metal. A free professional test at a reputable buyer confirms it for certain.

Is gold jewellery without a hallmark worthless?

Not necessarily. Older, handmade or resized pieces can lose their stamp while still being solid gold. The only way to be sure is to have the metal tested. Bring it in and we will tell you exactly what it is at no cost.

Does broken or tangled gold still have value?

Yes. When gold is sold for its metal content, damage makes no real difference to the value. A broken chain, a bent ring or a single earring still contains the same gold and is paid for on weight and purity.

Why can you not give me a price over the phone?

Gold value depends on the live market price, which changes throughout the day, and on the exact purity and weight of your specific pieces. We need to weigh and test them in person to give you an accurate, honest figure rather than a guess.
