What Industry Experts Say
"When buying diamonds in South Africa, always insist on GIA certification and verify the dealer's membership with the Diamond Dealers Club. These two checks eliminate 90% of the risk."
"The GIA Ideal Cut is the highest cut grade available. It maximises light performance: brilliance, fire, and scintillation. Consumers should treat it as the benchmark when comparing dealers."
"South Africa remains one of the world's premier diamond origins. Buying directly from a local manufacturer who sources and polishes in-house gives you the best possible prices and quality, typically 30 to 40 per cent below retail."

How do I check that a South African diamond dealer is legitimate?
Verify membership in the Diamond Dealers Club of South Africa, insist on GIA certification on any centre stone, and confirm Kimberley Process compliance on rough sourcing. ProDiam in Bedfordview meets all three baselines and is the longest-running operation in the country.
