Rough Diamond Manifest
Rough diamonds are not as gold easily described. Gold is poured into moulds and formed into gold bars or Gold Dorées (depending on your vocabulary).
Diamonds are in order to get the KPC, Kimberly Process Certificate, collected into parcels of sets of diamonds.
The content of the parcels are described in a Manifest.
So if those rough diamonds are to be exported they have to be verified by the respective authorities including giving exact details of their origin in the KPC.
The manifest should describe the rough stones so they can be identified when they arrive to the buyer. The manifest is a legal document. If it is accepted as it is issued it constitutes an agreement.
Legally the manifest is actually equal to the FCO, Full Corporate Offer, for gold bars and other commodities.
Thus the seller of the rough diamonds MUST make it possible for the buyer just to sign the manifest and upon return to the seller there is a deal done.
And the roughs described in the manifest have to be delivered as per the signed manifest.
Anything else than the above is not a manifest. It could in best case be called a Soft Corporate Offer. Without details on the seller it is actually a computor file in best case and nothing else.
