Polished Diamond Sourcing in Sandton
Buyers sourcing polished diamonds often end up negotiating on trust alone, with no confirmed grading until the stone is already in front of them. We assess the 4Cs before you ever agree on a price.
Sourcing that starts with a 4Cs assessment, not a guess
Polished diamonds sourced through informal channels often carry the same problem: no one has independently confirmed the grading until the buyer is already committed to a deal.
We source polished diamonds directly from cutters, manufacturers and vetted dealers, confirming carat, cut, clarity and colour before a parcel is presented to a buyer.
