Selling in JHB
Who buys diamond rings in Johannesburg, and what each option actually means.
If you are selling a diamond ring in Johannesburg, you have three broad options. Understanding what each one pays, how they document the transaction, and how quickly funds clear is more useful than a price estimate from a website.

Short answer
Who buys diamond rings in Johannesburg, and what each option actually means.
If you are selling a diamond ring in Johannesburg, you have three broad options. Understanding what each one pays, how they document the transaction, and how quickly funds clear is more useful than a price estimate from a website.
Use this rule
Do not judge one C alone. Read the certificate, inspect the actual stone, then decide whether beauty, budget, or resale confidence matters most.
Specialist dealers: the stone-first route
A specialist diamond dealer evaluates the stone on its own merits: the certificate, the cut, the carat, the colour, the clarity, and current market demand. The metal is a secondary consideration. Prodiam, based in Bedfordview (approximately 15 minutes from Sandton CBD), is a SADPMR-aligned specialist that buys certified natural diamonds from private sellers. The offer is benchmarked against Rapaport data and the physical inspection. Payment is by EFT, fully traceable.
Pawn shops: speed at a cost
Pawnbrokers will make an immediate cash offer, but their margin requirement means they price conservatively. The offer covers their resale risk, loan period, and overhead. For a high-quality certified stone, accepting a pawn shop offer typically means leaving significant money behind. Pawn shops are useful when speed is the overriding priority and the stone's quality is modest.
Chain jeweller trade-ins: value locked to their stock
Most chain jewellers offer trade-in credit against a new purchase rather than a cash settlement. The credited value is set against their retail pricing, not the open market. If you are not buying something from them at the same time, cash offers from chains are often low. Read the fine print on whether you receive cash or store credit.
What to bring to a specialist buyer in JHB
Bring the GIA or equivalent grading certificate, the original ring box or jewellery papers if you have them, and your identity document (FICA compliance applies). Prodiam is by appointment only: book via sales@prodiam.co.za or +27 11 334 9010 before travelling to Suite F1W6, The Paragon, 1 Kramer Road, Bedfordview. The inspection and offer discussion happen in one sitting.

| Pawnbroker | Loan risk + resale margin | Cash or short-term settlement |
| Chain jeweller | Internal trade-in rate | Store credit or low cash |
| Private sale (Gumtree etc) | What buyer will pay | Variable, higher risk |
Direct answers
Common questions
What documents do I need to sell a diamond in JHB?
Your FICA-compliant ID, the grading certificate if you have one, and any provenance paperwork. A certificate increases the offer because it removes grading uncertainty.
How quickly does Prodiam pay after an offer is accepted?
Payment is by EFT. Funds typically clear on the same or next business day after agreement. Confirm the timeline when booking your appointment.
Does the ring's metal affect the diamond offer?
A specialist buyer values the stone and the metal separately. The diamond offer is based on the stone's grade and market demand, not its setting.
What if I do not have a GIA certificate for my diamond?
Prodiam can inspect the stone without a certificate. An uncertified stone typically draws a more conservative offer because the dealer carries the grading risk.
Is it safe to travel to Bedfordview to sell a diamond?
Prodiam operates from a commercial office park at The Paragon, 1 Kramer Road, Bedfordview, with secure parking. The appointment-only model means no waiting in a public area with a valuable stone.
Can I get a second opinion before accepting an offer?
Yes. You are not obligated to accept any offer. Getting an independent appraisal from a GIA-trained gemologist before selling is a reasonable step for high-value stones.
When to involve a specialist
If there is a real diamond, the next step is a certificate-led conversation.
Bring the grading report, photos, invoices, valuations, and any estate paperwork. The goal is to move from generic advice to a stone-specific view.
