Black Diamond, also known as carbonado, is supplied by PT Golden Terrac International in a rough natural form. The material consists of natural carbonado and polycrystalline diamond, both recognised for exceptional toughness in industrial applications. The supplier notes that carbonado is one of the toughest natural diamonds, making it suitable for drilling, cutting and polishing tasks. In the global market, rough black diamonds are typically traded in carat weights ranging from half a carat to several kilograms, and are valued for their durability rather than optical brilliance. Typical industrial users include mining equipment manufacturers, precision‑tool makers and high‑end gemstone cutters who require a material that can endure high impact and abrasive forces. As the listing does not disclose minimum order quantities, payment conditions or shipment details, interested importers should contact the supplier directly to negotiate these terms and to obtain any required certification documents.

Before placing an order, request a detailed assay report that confirms the carbon content and any trace mineral presence. Verify whether the supplier can provide a Kimberley Process Certificate or equivalent documentation, as some jurisdictions require proof that the diamond is not conflict‑origin. A sample piece, even a small fragment, can help assess the material’s homogeneity and suitability for your intended industrial process.
Discuss logistics early by asking which Incoterms the supplier can accommodate, such as FOB Los Angeles or CIF New York, and confirm the expected lead time from mining to shipment. Clarify packaging specifications, including container type, moisture barriers and any special handling instructions needed for a brittle mineral. Agree on payment terms, for example a 30 % advance via irrevocable LC with the balance payable upon presentation of the commercial invoice and inspection certificate.
Arrange for an independent inspection at the point of loading or at the destination port. The inspection should verify carat weight, density, hardness and any visible inclusions that could affect performance. Request the inspection report, a full set of shipping documents and a certificate of origin to ensure smooth customs clearance and to protect against potential disputes.
