Sell your jewellery to the people who remake it.

Sell to a manufacturer, not a reseller. A second-hand dealer or pawnshop discounts your jewellery for the risk of holding and re-selling it as-is, so their offer is a fraction of the real worth. Prodiam is a Bedfordview cutting house: we re-cut, re-set and re-supply the diamonds and refine the metal, so we value the assets themselves. Diamonds are benchmarked to the Rapaport sheet, gold and platinum to the metal spot, and the working is shown to you before you decide.

A piece of jewellery is usually two values added together: the metal and the stones. The metal is its weight times purity times the day’s spot price. Natural diamonds are valued against the Rapaport sheet with documented adjustments for cut, clarity, colour and certification. Costume value, brand markup and the original retail price do not carry over, what you are paid is the honest asset value, benchmarked to public references rather than an opaque margin.

Yes, this is a large part of what we do. We work with executors, deceased-estate attorneys and family beneficiaries, with FICA-compliant settlement paid direct to the estate account and a photographic record of every item valued. You must be the legal owner or hold written authority (letters of executorship, or the owner’s written mandate). Everything is handled confidentially, and there is no obligation to sell after a valuation.

Yes. A certificate helps us give a tighter figure up front, but if a stone is uncertified we can submit it to GIA South Africa, in the same building as our bench, and re-grade it before final settlement, faster than couriering it elsewhere. Either way the diamond is Rapaport-benchmarked and the metal is priced against the day’s spot.

Fundamentally, yes. A pawnshop values your jewellery at its resale-as-is risk and often pays a small fraction of true worth, in instant cash. As a manufacturer-direct cutting house and refiner, we value the diamond and the metal on what they are actually worth, because we can re-cut, re-set and refine, and we settle by verified bank transfer with full FICA paperwork. The trade-off is that we work by appointment to a benchmark, not cash over a counter, but the number is honest and the funds are clean.

Then trade up instead. Our Upgrade Promise lets you put the value of an existing piece toward something larger or rarer at the bench, with Prodiam-original stones earning the highest credit. Many clients sell one inherited piece and put it toward a ring they will actually wear. Tell us which you would prefer and we will show you both numbers.
