What Industry Experts Say

"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."
