Crystal Rio Export Import Lda supplies natural Blue Quartz rough material composed of SiO2 with dumortierite inclusions, sourced directly from primary deposits in Minas Gerais, Brazil. The material appears in irregular nodules and fracture-filled fragments, typically ranging from 20 mm to 150 mm in diameter, with color saturation varying from pale sky blue to deep indigo depending on dumortierite concentration. Each batch is hand-sorted to remove excessive matrix rock and surface dust, ensuring consistent visual quality for lapidary use.
This variety of quartz is not treated or dyed, and its natural hue stems from trace iron and dumortierite fibres aligned during crystallisation. Standard industry tolerance for foreign matter is under 3% by weight, and moisture content is typically below 0.5% when dried. The material is supplied unpolished, with surface textures ranging from slightly weathered to sharp-fractured, suitable for cutting into cabochons or carving. Buyers in the gemstone wholesale market prefer this grade for its structural integrity and predictable cleavage patterns during sawing.
Primary buyers include lapidary workshops in Europe and North America, specialty metaphysical distributors, and small-batch jewelry manufacturers seeking unique raw material for artisan pieces. The material is packed in 25 kg polypropylene bags, sealed against moisture, and shipped in standard 20 ft containers. Trade terms are FOB Rio de Janeiro, with bulk orders accepted for 500 kg minimum. Lead time is 10 to 14 days after payment confirmation, subject to port scheduling. Certification for mineral origin is available upon request, but no third-party gemological reports are routinely provided.

Before placing an order, verify the batch's color consistency by requesting a sample set from at least three different lots. Confirm the physical dimensions of the fragments and the percentage of material exceeding 100 mm in diameter, as this affects cutting efficiency. Request documentation that the material is free from radioactive elements or chemical treatments, especially if importing into the EU or North America.
Confirm the Incoterms as FOB Rio de Janeiro, and ensure the supplier provides a commercial invoice with HS code 7103.99. Other key terms to clarify include packaging weight per container, palletization method, and whether loading is included. Lead time is typically 10 - 14 days, but port congestion in Rio may extend this. Payment is usually via T/T in advance or LC at sight; avoid open account terms with new suppliers.
Upon delivery, inspect the material for foreign matter, moisture, and color variation against the sample. Use a 10x loupe to check for surface coatings or dye pooling. Retain a representative sample from each batch for quality audit. Ensure the supplier provides a declaration of origin and a packing list with gross/net weights. For customs clearance, the HS code must match the declared use: gemstone, mineral specimen, or raw material.
