Free Jewellery Valuation in Johannesburg: What It's Worth and How It Works

Most people have no idea what their jewellery is actually worth, and the jewellery trade is comfortable keeping it that way. An inherited ring, a gold chain that's gone out of fashion, a diamond piece bought years ago: all of it has value, but "value" means very different things depending on why you're asking. Here's what a real jewellery valuation involves in Johannesburg, and how to make sure the number you're given is honest.

Know which value you actually need

This is the first thing that trips people up. "What's it worth" has three different answers.

Insurance value. What it would cost to replace the piece new. This is the highest number, and it's what you want on your insurance policy. It is not what anyone will pay you for it.

Sale value. What a buyer will actually give you today. This is lower than insurance value, always, because it reflects real resale, not replacement cost. If you're selling, this is your number.

Estate value. Fair market value at a specific date, for winding up a deceased estate. This has to be done properly and on the record.

If someone hands you a single figure without asking which one you need, be careful. The oldest trick in the trade is quoting you a low sale price while letting you think it's the piece's "value."

What actually drives the value of jewellery

For gold pieces, the baseline is simple: weight and purity. Gold is priced by the gram, adjusted for karat. The higher the karat, the more actual gold is in the piece: 9ct is 37.5% gold, 14ct is 58.5%, 18ct is 75%, and 22ct is 91.7%. At recent 2026 rates, South African gold buyers have been paying in the region of R800 a gram for 9ct, R1,200 for 14ct, R1,600 for 18ct, and R1,900 for 22ct, though these move every day with the international gold price and the rand, so treat them as a guide, not a fixed quote. The sum itself is simple: weight in grams, times the purity for that karat, times the live gold price. That raw-material value sets the floor even for a piece that's out of fashion, and a broken or tangled piece still carries its full gold value because the metal can be refined. On top of the metal, craftsmanship and a recognised designer name, a Cartier or Tiffany piece for instance, can lift the value well above melt.

For diamonds, value comes down to the well-known four: carat (size), cut (how well it's cut, which drives its sparkle), colour (how white or tinted), and clarity (internal flaws). Two diamonds of the same size can differ enormously on the other three. To put rough numbers on it, a certified 1-carat natural diamond in South Africa in 2026 might retail anywhere from around R31,000 for lower colour and clarity up to R160,000 or more for a top D-colour, near-flawless stone. Lab-grown diamonds of the same size and grade sell for a fraction of that, often R8,000 to R30,000. Two cautions, though. Those are retail and market guide prices; what a seller is actually paid for a loose diamond or a diamond ring is well below retail, because the resale market for diamonds is far weaker than most owners expect. And a diamond's grades should be confirmed on a proper GIA or IGI certificate, not taken on trust. A good valuation assesses all four Cs and separates the diamond's worth from the gold or platinum it's set in.

For branded and designer jewellery, the name matters. A piece from a recognised house can be worth well above its gold-and-stone value because of the brand and the design. An unbranded piece of the same materials is valued closer to its raw components.

Condition matters across all of it. Damage, wear, and missing stones reduce value; original condition and any documentation increase it.

Why "free valuation" should mean genuinely free

A free jewellery valuation should cost you nothing and commit you to nothing. Be wary of anyone who offers a "free valuation" that quietly turns into pressure to sell on the spot, or who won't give you the number in writing. A real valuation is an honest assessment you can take away and act on however you choose, including walking out and thinking about it.

How to protect yourself

• Know whether you need insurance, sale, or estate value, and say so.

• Ask how they reached the number: metal weight and karat, the diamond's four Cs, any brand premium.

• Get it in writing.

• For anything valuable, get a second opinion before you sell.

• Never sell under pressure or on a "today only" deadline.

• Use a SAPS-registered buyer with secure premises.
