How are Rapaport Diamond Specifications (Rapaport Specs) assigned on RapNet?
As long as all your uploaded diamond data meets all the conditions listed in the particular RapSpec category, RapNet will automatically assign a Rapaport Spec to your uploaded diamond.
Example: If your diamond is Spec A3, you should compare the diamond data that you uploaded against the RapSpec A3 requirements (https://trade.rapnet.com/index.html#/RapSpecs)
How to list diamonds as RapSpec A1
To get a RapSpec A1, you need to meet the following conditions:
Your diamond must have RapSpec A1 parameters and have an RDC grading report.
Your upload file must include Seller Spec = A1.
If you are uploading using an inventory file, include the column header "Seller Spec", and the value be "A1".
If you are uploading a single diamond, enter A1 in the 'Seller Spec' Field Name. (https://technet.rapaport.com/Info/LotUpload/FieldsAndValues.aspx#SellerSpec)
