Diamonds (C)
Our complete end-to-end diamond logistics — from licensed alluvial mines to the world's leading trading hubs. We source Kimberley Process-certified rough diamonds directly from verified producers in the DRC, Angola, and Sierra Leone, delivering conflict-free industrial and gem-quality stones to refiners, cutters, and traders worldwide.
Diamonds — Mine to Market
Every parcel of diamonds follows a transparent 8-step journey from licensed African mines to international delivery.
Sourcing & Mining
Verified sourcing from licensed alluvial and small-scale mining cooperatives operating along East Africa’s alluvial diamond-bearing rivers. Each mining site is registered with national mining authorities, validated under the Kimberley Process Certification Scheme (KPCS), and audited for compliance with OECD Due Diligence Guidance. We work directly with cooperative leaders to ensure conflict-free, ethical extraction at every site.
Recovery & Initial Collection
Diamond-bearing gravel is processed through hand-shaken sorting screens and gravity sluices at the mine site to recover rough crystals. Each stone is collected, weighed on calibrated precision scales, and assigned a unique identification number linking it to the source mine and recovery date. Initial documentation begins here — creating the chain-of-custody record that follows the parcel through every subsequent stage of the supply chain.
Cleaning & Sorting
Recovered rough diamonds are cleaned, inspected under jeweler's loupes, and pre-sorted by size, shape, and quality classification. Stones are organized into preliminary categories — industrial, near-gem, and gem-quality — to streamline downstream grading and pricing. Kibal sorters operate under controlled, transparent conditions with chain-of-custody integrity maintained throughout every batch.
Grading & 4Cs Certification
Rough diamonds are professionally graded under gemological microscopes against the internationally recognized 4Cs standard — Carat, Cut potential, Colour, and Clarity. Where required, stones are submitted to independent laboratories such as the GIA or HRD Antwerp for full certification. Buyers receive detailed grading reports tied to the parcel's unique chain-of-custody record — providing complete confidence in the quality of every stone purchased.
Kimberley Process Compliance
Every export parcel is sealed in a tamper-evident KP-compliant container and accompanied by an official Kimberley Process Certificate issued by the country of origin's designated authority. The certificate carries a unique serial number, parcel weight, value, and country of origin — guaranteeing the diamonds are conflict-free under United Nations resolutions. Additional OECD due-diligence and origin documentation completes the compliance package.
Secure Transport
Sealed KP-certified diamond parcels are transported in tamper-evident security cases by armed bonded couriers from the regional valuation office to the international export point. Every movement is comprehensively insured, GPS-tracked, and coordinated with specialist precious-cargo security partners. Dedicated logistics managers monitor each consignment in real time to ensure chain-of-custody integrity from origin to international gateway.
Export & Customs Clearance
Full export documentation is prepared and submitted: Kimberley Process Certificate, customs declarations, parcel-weight verifications, and bills of lading. Customs officials physically verify the KP seal and parcel content against the certificate before authorising export. Our regulatory team navigates the export procedures of each African origin country, ensuring smooth, compliant clearance without delays for time-sensitive precious-cargo shipments.
International Delivery
Bonded delivery to the world's leading diamond trading hubs — Antwerp, Dubai, Mumbai, and Tel Aviv. Sealed parcels are handed over to bonded receiving agents at the destination's secure terminal, with full insurance covering transit value end-to-end. CIF, FOB, and DAP delivery terms are available to suit buyer requirements. Final document exchange and payment settlement complete each transaction, with the customer relationship maintained for future trade.
