Rough Diamond Supply
Nexus reviews natural rough diamond parcels from direct producers, titleholders and Authorized Contracting Sellers with verifiable access to the supplying entity. Each opportunity is assessed parcel by parcel for origin, current location, carat weight, size distribution, quality profile, title, export authority, Kimberley Process documentation, inspection pathway and commercial basis. Availability and price are confirmed only in a current written offer.
Role and availability are transaction-specific. Nexus may act as contracting seller, authorized commercial representative or transaction coordinator. Its exact role, authority and responsibilities are stated in the applicable offer or agreement. Product availability is not continuous or guaranteed; quantity, location and commercial terms must be confirmed in writing.
Nexus distinguishes market context from a firm commercial offer. The benchmark, unit, pricing period and contractual adjustment must all be explicit.
Parcel-specific commercial basis
Parcel-specific valuation
Rough diamonds do not have one exchange-traded benchmark. Price is established for the identified parcel after document review, inspection, weighing, sorting and agreed valuation.
Offer-specificUSD/carat

Is there one public benchmark price for rough diamonds?
No. Rough diamond value is parcel-specific and depends on the stones’ size distribution, shape, colour, clarity, origin, expected recovery and current market conditions. A commercial offer must identify the exact parcel and valuation basis.
Are rough diamonds continuously available?
No. Availability, quantity, origin, current location and Nexus’s role vary by opportunity and are confirmed only in a current written offer or agreement.
What must a supplier provide before a parcel advances?
The supplying entity must support its identity, title or contracting authority, origin, current location, parcel details, export pathway and applicable Kimberley Process documentation, and permit direct verification and controlled inspection.
