How much do South African jewellers mark up diamonds?

Question

Accepted Answer

A typical South African retail jeweller marks a one-carat round-brilliant up two to four times the wholesale price. The wholesaler’s margin sits between ten and twenty per cent. On a one-carat GIA-equivalent stone, the price gap between the retail and wholesale channels usually falls between thirty and sixty per cent. On larger stones the gap widens. The retail multiple of two to four times the wholesale price is not unique to diamonds; it is roughly what every premium-retail category runs at. The mark-up is not greed in any straightforward sense, it covers shop rent on a high-street retail floor (six-figure-monthly in Sandton or the V&A Waterfront), sales staff on commission, insurance on stock, marketing in glossy print, and inventory that sits on the floor for months before it sells. What this means for a buyer is simple. Every rand spent above the wholesale price is paying for the experience and the brand, not the stone. If the experience and the brand matter, the spend is rational. If the math is the priority, and the buyer is comfortable with a technical conversation in an office without champagne, the wholesale channel exists, has never been a secret, and saves between thirty and sixty per cent.
