Cut, recut,
repolish.

Tolerance ±0.05 mm / Minimum 0.20 ct / Lead 2–6 wk / Diamond & coloured stones

Rough planned for yield, cut to a written plan. Worn stones recut for light — trade and private work on the same terms as the group’s own desks.

I.   The services

Six lines on the job sheet.

From mine-fresh rough to a heritage recut. Assessment opens every job; the stone dictates the rest.

Cutting of rough.

Rough planned and cut to finished stones — yield mapped, colour oriented, angles held to tolerance. Brilliant, step, mixed or fancy.

PathRough → polished
Lead2–4 wk

Recutting.

Chipped, abraded or badly-proportioned stones recut for symmetry and face-up, keeping every point the plan allows.

Wt loss3–15%
Lead1–3 wk

Repolishing.

Faces and girdles brought back to lustre — surface work only, no change of proportion. Ready for re-grade.

ScopeSurface only
Lead3–10 d

Calibration.

Matched pairs, suites and graduated sets cut to uniform dimension. Tolerance agreed in writing before the wheel turns.

Tol±0.05 mm
Lead2–5 wk

Bespoke design.

Original faceting designs and non-standard work — portuguese, barion, concave. Per-stone consultation on what the rough will bear.

BasisBy commission
Lead4–8 wk

Origin & treatment advice.

A written pre-submission read on origin and treatment likelihood, and which laboratory suits the material. Not a lab report.

OutputWritten opinion

Four stages, every stone. Nothing starts until the plan is signed.

24–72 hrs

Receive.

Logged, weighed, photographed against a neutral plate. Insured inbound; confirmation the same day.

3–7 days

Assess.

Inclusions mapped, yield estimated, the plan written — design, tolerance, turnaround, price. You approve in writing.

1–6 wks

Work.

Cut to plan — checkpoint photography at rough-in, faceting and polish. Deviations re-quoted before proceeding.

3–5 days

Return.

Final inspection, a dossier of finished measurements. Insured return — or direct to the lab.

III.   The materials

Hard stones, soft hands.

Diamond and corundum take the precision work; softer material takes different speeds and different laps.

Diamond & corundum

Mohs 9–10 · Scaif & bonded wheels

Cast-iron scaif for diamond, bonded wheels for corundum; separate equipment for natural and lab-grown.

  • Diamond 10
  • Ruby 9
  • Sapphire 9
  • Chrysoberyl & alexandrite 8.5

Coloured & semi-precious

Mohs 6.5–8.5 · Cerium & tin laps

Different speeds, different laps. Emerald handled with particular care — filled fissures logged before any work begins.

  • Spinel 8
  • Topaz & aquamarine 7.5–8
  • Emerald 7.5–8
  • Tourmaline & garnet 7–7.5
  • Tanzanite & peridot 6.5–7
Nothing begins on the wheel until the plan is on paper and the client has signed it.

IV.   The workshop

Behind the bench.

Two benches, Bangkok and Colombo, run as one workshop: same cutters, same standards, same plan-before-wheel protocol.

Bangkok works the full range; Colombo specialises in sapphire and the Ceylon tradition. Trained in Antwerp on diamond, in Bangkok on colour — over a decade at the wheel.

Every stone is cut by the cutter who agreed the plan. Estate stones and insurance recuts are routine.
