Before you buy

Common questions

Is it legal to buy gold from Sierra Leone?+
Yes — provided it is handled by a licensed dealer and exporter registered with the National Minerals Agency. Every export is assayed, valued and certified, with statutory duty paid to Government. Nova Parameter operates only within that framework.
How do I know the purity is real?+
Gold is assayed before export in the presence of the exporter, a Senior Mines Monitoring Officer and a customs officer. A certificate is issued stating weight, purity, licence number and value — issued by the authority, not by us.
Are the diamonds conflict-free?+
Sierra Leone is a full participant in the Kimberley Process Certification Scheme. Every rough parcel we export is sealed and accompanied by a serial-numbered Kimberley certificate confirming lawful, conflict-free origin.
What volumes do you work with?+
We supply bullion in 1kg and custom formats, refined dust by verified weight, and graded rough parcels. Pricing tracks the live spot. Contact the desk for current availability and formal terms.
