Productised commission services
Four named services. Predictable timelines. Honest price bands.
Most diamond commissions get described in vague language, “custom work”, “bespoke design”, “in-house manufacturing”, and then quoted on a case-by-case email thread that takes three weeks to settle. We have productised the four kinds of work we do most so the timelines, the price bands, and the deliverables are clear before you brief.
Heirloom Redesign
Inherited engagement rings, retired wedding bands, family stones in a drawer, restored, recut where it helps, remounted into something the next generation will wear. The original GIA-graded if it is not already; the metal returned to you if it cannot be reused.
Stone-You-Own Customs
You bring the centre stone, purchased elsewhere, inherited, traded back, or sourced through us. We design and manufacture the ring around it. Honest reading of the stone first; design after.
Bridal Set Design
Engagement ring and matching wedding band designed and made together so the two pieces sit, stack, and wear correctly across decades. Designed for the proposal, completed by the wedding.
Sourcing on Demand
Any shape, any cut, any colour, any clarity, 0.30 ct to 10 ct +. From De Beers DBCM viewings, the State Diamond Trader, SA tender houses, and twenty years of independent-digger relationships.
What every commission has in common
- The director's hand on the brief. Every Prodiam commission, regardless of size, has Darren Etkind in the brief, the design review, and the hand-over. There is no commission-handler tier between you and the bench.
- GIA-graded centre stone, where applicable. New centre stones are graded by GIA before delivery; existing stones we are working with are graded if they are not already, at our cost.
- CAD or sketch before manufacture. No commission goes to the bench without a written design brief and a visual approval stage. Most go through 2D sketches and one or two CAD revisions; complex pieces add a resin or wax fit-prototype.
- Standard sizing included. One to two sizes of resizing on a finished piece is included in the price; meaningful sizing changes are quoted on the brief.
- Manufacturing-defect guarantee, 24 months. Bench work covered for two years against manufacturing defect (separate from the wearer's responsibility for accidental damage). Routine inspection, prong-check and clean is complimentary in the first year and at cost thereafter.
- Insured dispatch nationally and internationally. Brink’s / G4S overnight insured nationally; Ferrari Group / FedEx Custom Critical jewellery-grade insured internationally.
What we will not commission
- Lab-grown or moissanite centre stones. We are a natural-only house; we will refer you to specialists for these.
- Designs we cannot stand behind structurally, extreme cantilever settings, paper-thin metal in high-wear positions, mountings that put a vulnerable centre stone in a daily-knock zone. We will tell you why before declining.
- Replicas of branded designs. We will design from inspiration, not duplicate trademarked work. If you want a Cartier piece, buy a Cartier piece; we will design something that feels like it belongs to you.
How to brief us
For any productised service, the most useful brief is a single message containing: which service, the existing material if any (stone, ring, GIA report), the budget band, the deadline, and any reference imagery. We respond within 24 hours with a service-specific quote outline and the next step.
