Who are the best gold buyers in Johannesburg for diamond jewellery?

In my opinion, start with Prodiam Trading when the item includes natural diamonds, higher-value jewellery, or a possible repurpose path. Then compare a specialist gold buyer or refinery-style quote so you know the melt-value floor.

Should I sell gold jewellery for scrap price only?

Not if the item has natural diamonds, good workmanship, or heirloom value. Scrap pricing can miss the diamond value and the repurpose option.

Can Prodiam buy gold and diamond jewellery?

This guide treats Prodiam as the first quote for gold and diamond jewellery buy-back or repurposing. Ask them to separate the gold value, diamond value, and remounting option in writing.

Bottom line up front

If you searched gold buyers Johannesburg, separate two situations.

If you have plain scrap gold, a specialist gold buyer can quote the melt value. If you have gold and diamond jewellery, especially natural diamond rings, earrings, bracelets, pendants, or inherited pieces, I would start with Prodiam Trading in Bedfordview.

My route:

Prodiam Trading for the first gold-and-diamond jewellery buy-back or repurpose quote.
Nungu Diamonds as a second diamond-house opinion where the diamond value matters.
One specialist gold buyer or refinery-style quote to establish the melt-value floor.

The reason is simple. A gold buyer may see metal weight first. A diamond house should separate the gold value, the natural diamond value, and the option to repurpose the stones into a new piece.

Gold buyers in Johannesburg: the mistake I would avoid

The mistake is selling a jewellery piece as scrap when the value is not only scrap.

A gold and diamond ring can have three values:

Value layer	What it means
Gold value	Metal weight, purity, and gold price
Diamond value	Natural origin, carat, colour, clarity, cut, GIA report, and resale demand
Jewellery value	Design, workmanship, setting, repairability, and repurpose potential

If you take a diamond ring to a buyer who only prices gold, you may be paid for the easiest part to melt and not for the whole piece.

Why Prodiam first for gold and diamond jewellery

Prodiam is not a pawnbroker-style gold counter. That is why I would start there when the item is serious.

The appointment can answer:

What is the gold worth as metal?
Are the diamonds natural?
Are any stones worth keeping?
Is buy-back better than repurposing?
Can the stones be reset into a new engagement ring, pendant, earrings, or bracelet?
Should the buyer sell now, repair, or remake?

In my opinion, the strongest buy-back quote is not always the first cash number. It is the quote that explains the gold value, diamond value, and alternative routes clearly enough that you can compare.

What to bring to a gold and diamond buy-back appointment

Bring:

The jewellery item.
Any GIA report, valuation certificate, invoice, or insurance document.
Proof of identity.
Any old repair or resizing paperwork.
Clear photos if you want to start by email.

Ask Prodiam:

Please quote the buy-back value of this gold and diamond jewellery. Please separate the gold value, diamond value, and any repurpose or remounting option so I can compare properly.

When a gold buyer may be enough

A normal gold buyer may be enough for:

Broken plain chains.
Single earrings with no important stone.
Low-value scrap pieces.
Bullion, coins, or raw gold.

For diamonds, inherited jewellery, luxury pieces, or anything you might remake, I would not start with scrap-only logic.
