Planning, per parcel
I.   The grade

The four C's, at the desk.

Weight, colour, clarity and cut — read across a parcel, not a campaign.

Carat

Weight is where the desk starts.

Targets set in writing — sieve range for parcels, exact weight for principal stones — matched to the report at exit.

Colour

Colour needs two languages.

D-to-Z for whites, fancy grades for the rest, against master stones held in-house.

Clarity

Clarity belongs under tools.

10× loupe, microscope where it matters.

Cut

Cut is the only C the cutter truly owns.

Make, polish and symmetry checked against the planning file. PrecisionCut recuts when the rough deserves it.
