Sell to Prodiam · Diamonds, gold & jewellery buy-back
We buy diamonds, gold, and any jewellery they sit in.
Diamonds, certified or not. Gold of any karat, in any form. Any jewellery that contains either, engagement rings, tennis bracelets, tennis necklaces, pendants, chains, signet rings, signed pieces, whole estates, single inherited stones. Most jewellers buy second-hand at thirty cents on the rand. They have to: they do not cut, they on-sell. We do cut. We re-set. We re-supply. We refine the metal in-house. So we can pay closer to honest market, the diamond against the Rapaport sheet on the day, the gold against the LBMA spot price.
Why sell to Prodiam
Six reasons it’s the better number.
-
We cut. So the value is real.
A retail jeweller on-sells your stone in its existing form, so they discount aggressively for risk. We can re-cut, re-set, or re-supply, so we value the stone, not the resale-as-is.
-
Rapaport-benchmarked.
Every offer is anchored to the Rapaport price list on the day, with documented adjustments for cut, certification, fluorescence, and current SA market spread.
-
Same-address re-grading.
If your stone has no cert, we can submit it to GIA South Africa, in the same building, before final settlement. Faster than couriering it elsewhere.
-
FICA-compliant settlement.
Bank transfer to a verified SA account, full provenance paperwork, FICA / KYC done correctly. No envelope-cash ambiguity that could cause SARS or banking issues later.
-
Cleared funds, fast.
From signed offer to cleared ZAR in your account: typically 72 hours for SA buyers, 5 days for international wires. No consignment lock-in.
