Polished Diamond Evaluation in Sandton
Selling a polished diamond without an independent 4Cs assessment means negotiating on the buyer's terms. We grade carat, cut, clarity and colour before you talk price with anyone.
An honest 4Cs assessment before you sell
Polished diamond value depends on a specific combination of carat, clarity, colour and cut, and most sellers only have an estimate rather than a proper assessment. That gap is exactly where buyers negotiate a lower price.
We evaluate polished diamonds at our Sandton offices, giving you a documented 4Cs valuation before you agree to sell to anyone.
