What a diamond cutting works does, and the few that cut in South Africa.
A cutting works is where rough diamonds become finished, polished stones. South Africa mines a great deal of rough but cuts only a fraction of it domestically. We are one of the licensed works that does, on a bench in Bedfordview, Johannesburg.
What a diamond cutting works actually does
Cutting is the craft of turning a rough crystal into a polished diamond that returns light. The work runs from planning the rough, where a single decision about how to divide a stone can change its value, through cleaving or sawing, bruting the outline, and polishing the facets to final proportions. A works is judged on the make it produces: the proportions, symmetry, and polish that decide whether a stone looks bright and lively or dull.
Why so few diamonds are cut locally
For decades most South African rough was shipped abroad for polishing, to Antwerp, Mumbai, and Surat, where cutting is done at scale. Beneficiation is the policy of adding that value at home instead. It is not simple to do. A works needs reliable access to rough, a SADPMR beneficiation licence, and the skill to cut at a grade that makes the economics work. Those barriers are why the list of genuine domestic cutting works is short.
What makes a cutting works legitimate
- A SADPMR beneficiation licence. The lawful right to take possession of rough and polish it, with auditable records of every parcel.
- Reliable rough access. Sightholder or Emerging Beneficiation Customer status, so the bench has stones to cut on a predictable cadence rather than chasing spot tenders.
- A real cutting standard. Cutting to GIA Excellent or AGS Ideal, not beneficiating good rough into weak, low-yield stones.
- A provenance trail. Kimberley Process compliance and documented chain of custody from rough to polished.
