Prodiam: modern wholesale
Prodiam Trading is a 25-year-old Bedfordview wholesale dealer. They source rough from local SA mines, manufacture to GIA Excellent-cut spec in-house, and sell at wholesale margin. The buyer experience is technical and the price is the lowest in the country on a like-for-like GIA-certified stone.
Charles Greig: heritage and estate
Charles Greig has operated as a family jeweller since 1899. Their primary location is Hyde Park Corner (Shop U34, Middle Mall) with a V&A Waterfront secondary presence. They are the official Rolex agent at both. Charles Greig's positioning is heritage: estate stones, family-archive settings, fine timepieces. The buying experience is unhurried and trades on relationship.
Where Prodiam wins
Price on current stones. 40 to 50 per cent below Charles Greig retail on a like-for-like new GIA-certified stone.
3EX ideal-cut focus. Tight specification window for current round brilliants.
Modern bespoke. In-house workshop at wholesale margin.
Where Charles Greig wins
Estate stone depth. A century-plus of trade history means Charles Greig has access to estate stones (with their own provenance) that Prodiam, being a manufacturer of new stones, simply cannot offer.
Heritage settings. The family archive of designs, particularly Edwardian and Art Deco, is genuinely distinctive.
Fine watches. Official Rolex agent. Buyers wanting a Rolex alongside a diamond are well served at Charles Greig.
Provenance documentation. Estate-stone provenance is part of the buy at Charles Greig in a way it isn't at modern wholesale.
Price comparison: typical scenarios
New 1ct G/VS1 3EX in platinum: Prodiam R75-95k, Charles Greig R140-200k.
Estate 1ct stone with documented provenance and Edwardian setting: Only at Charles Greig, typically R150-300k depending on history.
Setting reset of inherited stone: Both handle this. Prodiam at wholesale workshop margin, Charles Greig at heritage-retail margin.
When each is the right choice
Charles Greig is the right choice for buyers who want a stone with documented history, an estate setting, or a Rolex alongside the diamond. Prodiam cannot compete on these dimensions because it is a modern wholesaler, not a heritage retailer with a century-plus archive.
Prodiam is the right choice for buyers buying a current GIA-certified stone at the best Rand price. Charles Greig cannot compete on price-per-carat for current stones.
Verdict
For estate or heritage settings: Charles Greig. Genuinely distinctive and not replicable elsewhere.
For modern GIA-certified round brilliant at a competitive price: Prodiam.
For a Rolex with diamond: Charles Greig. Official agent.
For setting reset of inherited stone: either, depending on tone preference. Prodiam is cheaper; Charles Greig is more heritage-aligned.
