从China供应商批量进口A Class South Africa Bule Quartz

A class South Africa blue quartz from Ningbo Xiaotong International Trade Co., Ltd is a macrocrystalline variety of silica with a distinctive blue hue, sourced from South African mines but processed and exported from China. The material has a hexagonal crystal system, a hardness of 7 on the Mohs scale and a formula weight of 2.65 g/cm3, making it durable for jewellery and industrial applications.

The supplier’s processing flow includes sorting by colour intensity, precision cutting to customer specifications, sizing to standard gemstone grades, pressing for structural integrity, polishing to a high gloss and a final quality control check. Typical industry standards for polished quartz include a gloss level above 95 GU, with thickness tolerances of ±0.1 mm and diameter tolerances of ±0.3 mm. The blue colouration is usually consistent, though natural banding or inclusions may appear in some batches.

This quartz is used by jewellery designers for beads, cabochons and faceted stones, as well as by manufacturers of electronic components and decorative items. Ningbo Xiaotong International Trade Co., Ltd offers custom processing based on customer drawings or samples, with a minimum order quantity of 500 pieces. Packaging options include individual plastic bags for small pieces or padded boxes for larger stones, with incoterms available as FOB Ningbo or CIF.

Ningbo Xiaotong International Trade Co., Ltd is based at No 188 Wusheng Big Road in Yuyao, Zhejiang Province, China, a location that provides access to major export routes via Ningbo port. The company is categorised as an imported-tier supplier with a harbor trust tier, indicating it facilitates international trade for mineral and gemstone products.

The supplier’s profile highlights its ability to process quartz and other gemstones according to customer-provided drawings or samples, with a stated MOQ of 500 pieces. However, the listing shows a 0.00 response rate and no recorded average response time, so buyers should plan for direct outreach and allow extra time for confirmation of technical details or order specifics.
