Gold · Bought, refined & benchmarked · South Africa
Gold, valued honestly and refined in-house.
Prodiam is a working cutting house and gold refiner in Bedfordview, Johannesburg. We buy gold in almost any form, jewellery, scrap, coins, bullion, price it live against the LBMA gold-spot rate, and show you the working before you decide. And because we are a diamond house too, a piece with a stone in it is valued on both the metal and the diamond, not just the gold. This is the way in, whether you are selling, valuing, or trading up.
The short version
Your gold is worth the fine-gold price per gram times its purity times its weight, less an honest refining margin. We buy any karat, in almost any form, and refine it ourselves, so we carry less cost than a shop that sends it away and can settle closer to the real spot. The stones are always valued and paid separately. Everything below routes you to the detail: the value calculator, the sell pages, and the buy-back form.

Why the number is better here
The refiner, not a link in the chain.
Refined in-house
We do not pay a third party to process what we buy, so the cost a middle-man passes on to you is not in the number.
Priced against the LBMA spot
The metal is valued on the live London gold-spot rate on the day, in rand, with the karat confirmed on our own scale.
Gold and diamonds together
A ring with a stone is two assets. The diamond is valued against Rapaport and paid on top of the metal, never quietly kept.
FICA-compliant, cleared fast
Verified bank transfer, full paperwork, typically cleared within 72 hours. Clean, traceable funds, not envelope cash.
Gold, plainly
Frequently asked questions.
What is my gold worth?
Its metal value is the day’s fine-gold price per gram times the purity of your karat times the weight, before the refining margin. A gram of 9 ct is 37.5% of the fine-gold price, 18 ct is 75%. Our gold price per gram page has the full purity table and a calculator you can run on today’s figure. If a piece also holds a natural diamond, that is valued separately against the Rapaport sheet and paid on top.
Does Prodiam buy gold, or sell it?
We buy gold from the public and refine it in-house: jewellery, scrap, broken pieces, coins and bullion, priced against the live LBMA gold-spot rate, with FICA-compliant settlement cleared in about 72 hours. On the selling side, our own fine jewellery is made in gold and platinum. What we do not do is trade loose bullion or buy raw, unwrought gold from the public, which is tightly controlled under South African law.
Why sell gold to a refiner instead of a cash-for-gold shop?
Most gold buyers are a step in a chain: they buy from you and sell on to a refiner, so they quote a single blind number well under the real price and keep the gap. Prodiam is the refiner. That removed cost is what lets us price closer to the live spot, and we show you the working, the karat, the weight on our scale, and the margin, rather than one take-it-or-leave-it figure.
Where are you, and how does it work?
Prodiam is at Suite F1W6, 1 Kramer Road, Bedfordview, on the east of Johannesburg, seen by appointment so there is no counter queue. Send a photo and the weight first for an indicative figure, bring the gold in or post it insured, and we confirm the karat and weight in front of you before making a firm offer. Settlement is by verified bank transfer with full FICA paperwork.
