How to choose a diamond dealer in South Africa

Regulatory registration and compliance

A legitimate SA diamond dealer must be registered with the SADPMR (SA Diamond and Precious Metals Regulator). Ask to see the registration. FICA compliance is also non-negotiable: the dealer will ask for your ID and proof of address, and that is correct behaviour. Any dealer who skips this process is not operating lawfully. Prodiam is SADPMR-aligned and follows full FICA procedure on every transaction.

Certificate literacy and honest grading

The dealer should read a GIA or equivalent grading report with you, not just hand it over. Ask what the table percentage, depth, symmetry, and polish grades mean. A specialist can explain each field without hesitation. If a dealer focuses only on carat weight and neglects cut or clarity data, that is a gap in their competence. Prodiam works with certified natural diamonds and reads certificate data in detail with clients.

Transparent valuation method

Ask: how does the dealer arrive at a buy or sell price? A reputable dealer will reference Rapaport benchmarks, certificate data, current market demand, and the stone's physical condition. Vague answers like 'market rate' or 'our own assessment' without backing data should prompt further questions. Get the valuation method in writing before agreeing to anything.

Physical premises, payment trail, and operating history

Never transact with a dealer who insists on a parking lot or stranger-meet arrangement. A registered SA diamond dealer has a verifiable physical address. Prodiam operates from Suite F1W6, The Paragon, 1 Kramer Road, Bedfordview, Johannesburg, by appointment. Payment should be traceable: EFT with a business account, not cash-in-hand for high-value stones. Prodiam has established operating in the SA market. That track record is a concrete data point, not a claim.

Common questions

Does every SA diamond dealer need SADPMR registration?

Yes. Any dealer buying or selling rough or polished diamonds in South Africa must be registered with the SADPMR. Trading without registration is unlawful.

Why does a dealer ask for my ID when I sell a diamond?

FICA requires dealers to verify the identity of clients in transactions above certain thresholds. It is anti-money-laundering law, not optional.

Is a GIA certificate the only acceptable grading report?

GIA is the global benchmark. AGS and certain other labs are respected. In-house valuations from non-independent sources carry less weight for resale or insurance.

Can I sell a diamond without a certificate?

Yes, but without a grading report the dealer must physically assess the stone. The offer will typically be more conservative because grading risk sits with the buyer.

How do I verify a dealer's operating history?

Ask for their SADPMR registration number, check CIPC registration, and ask for client references. Years in a fixed commercial address is also verifiable via property records.

Is Prodiam the right dealer for both buying and selling?

Prodiam handles both. Book an appointment at Suite F1W6, The Paragon, 1 Kramer Road, Bedfordview, or call +27 11 334 9010 to discuss your transaction before attending.
