Parcel buying
A practical brief for buying diamond parcels
Parcel buying needs a different specification from single-stone sourcing. Define tolerance ranges, assortment and yield before comparing offers.
Define acceptable ranges
Document shape, sieve or size range, color, clarity, cut and total weight. State whether mixed grades or shapes are acceptable.
Request representative evidence
Ask for current parcel media, weight and piece counts, plus a clear description of how the parcel was sorted.
Confirm inspection and terms
Agree how discrepancies are handled before payment or shipment. Confirm availability and commercial terms directly with the supplier.
