Import Emerald — Buy in Bulk from Supplier in Brazil

Emeralds supplied by Raphael Duarte Costa are Grade A stones sourced from Brazilian mines, characterized by natural coloration and minimal inclusions. Each gem is untreated, preserving its original optical properties, with typical dimensions ranging from 2.5 mm to 8 mm in diameter and cuts including oval, emerald, and round. The stones exhibit medium to dark green tones with moderate saturation, consistent with the standard for Brazilian emeralds in commercial jewelry supply.

These emeralds are classified under the GIA system as Grade A, indicating a clarity level with slight inclusions visible under 10x magnification but not to the naked eye. The material is not enhanced by oiling or resin, and surface fractures remain untreated. Standard packaging is in padded foam-lined boxes with individual compartments, designed to prevent scratching during transit. The origin from Brazil is significant, as Brazilian emeralds are known for their lower iron content compared to Colombian stones, resulting in a slightly cooler green hue.

Buyers include jewelry manufacturers in Europe and North America who require consistent supply for mid-to-high-end collections. The stones are commonly set in gold or platinum rings, pendants, and earrings. Trade terms are typically FOB Santos or CIF port of destination, with minimum order quantities negotiable per batch. Buyers should request batch-specific certification and verify the absence of fracture filling before final payment.

Raphael Duarte Costa operates as an imported gemstone supplier based in Brazil, with no public profile beyond the listing. The supplier is verified through harbor trust tier, indicating compliance with basic export documentation and customs clearance. There is no information on mine ownership, processing facilities, or years in operation. Response rate and average response time are not recorded, suggesting limited buyer communication capability.

The supplier does not claim certifications, revenue, staff size, or client names. The listing reflects a direct sourcing role from Brazilian mines, with no indication of refining, cutting, or in-house grading. Buyers should treat this as a raw material conduit, not a finished goods manufacturer. Due diligence on origin traceability and treatment status is recommended before order confirmation.
