LUKONGE INTERNATIONAL GROUP supplies natural diamond stones graded as Diamond C, sourced directly from Tanzanian mining operations. Each stone is evaluated for carat weight, color grade, and clarity under standard gemological protocols, with typical ranges from 0.25 to 5.00 carats and color grades ranging from G to J. Clarity varies from SI1 to VS2, consistent with commercial-grade diamond supply for jewelry manufacturing. The stones are unheated and untreated, with no surface enhancement applied.
The material is natural diamond with a cubic crystal structure, exhibiting refractive index values typical of gem-quality diamond (2.417 - 2.419). Cut types include round brilliant, princess, and emerald, aligned with industry standards for jewelry settings. These diamonds are not lab-grown and carry no synthetic additives. Packaging is in sealed, tamper-evident containers with individual lot tracking, following standard industry practice for high-value gemstone export.
These diamonds are primarily purchased by jewelry manufacturers in Europe, North America, and Southeast Asia for use in engagement rings, luxury watches, and custom high-end pieces. Buyers include mid-tier designers sourcing for volume production and boutique ateliers requiring consistent stone quality. Trade terms offered include FOB Dar es Salaam and CIF major ports, with payment via T/T or L/C. Minimum order quantities are negotiable based on stone grade and total carat volume, and export documentation includes Kimberley Process certificates where applicable.

LUKONGE INTERNATIONAL GROUP operates from Dar es Salaam, Tanzania, with a physical address on Old Bagamoyo Road. The company is registered as an organic-tier supplier with voyage-level trust verification, indicating active engagement in international trade but without third-party certification or audited financial disclosures. The listing confirms export experience in diamonds but provides no details on years in operation, employee count, or client names.
The supplier does not claim ownership of mines or processing facilities. It functions as a trading entity sourcing stones from local networks and coordinating export logistics. There is no mention of in-house grading labs, certification issuance, or direct mining operations. Response rate and average response time are not tracked, suggesting limited real-time communication capacity. Buyers should treat this as a sourcing intermediary with documented export capability but unverified internal quality control systems.

Before ordering, verify the exact color grade, clarity, and carat distribution of each lot. Request written confirmation of treatment status and origin documentation. Confirm that the supplier can provide Kimberley Process certificates for each shipment, and ensure the documentation matches the declared quantity and weight. Do not rely on marketing language - demand lab-grade data for high-value lots.
Confirm the Incoterms (FOB Dar es Salaam is standard) and whether insurance is included. Lead time for export documentation is typically 5 - 10 business days after payment. Payment terms are T/T or L/C; avoid advance payments without third-party escrow. Shipping is usually via air freight for small lots, with sea freight for bulk. Ensure the consignee has customs clearance capacity in the destination country.
Inspect each batch for consistency in color, clarity, and cut upon receipt. Use a 10x loupe to verify inclusions and surface characteristics match the description. Request a sample of 5 - 10 stones per lot for pre-shipment review. Documentation must include a packing list with lot numbers, carat weights, and certification references. Retain samples for quality audits and dispute resolution.
