Import Blue Tanzanite Gemstone Plain Cabochons — Buy in wholesale FOB from Supplier in India

H S R ENTERPRISES supplies blue tanzanite plain cabochons from Jaipur, Rajasthan, a city with a centuries-old gemstone cutting and jewellery manufacturing tradition. The stones are offered in mixed shapes, including round, oval and irregular freeform profiles, with dimensions varying across individual pieces. Tanzanite rates 6 to 6.5 on the Mohs hardness scale, making it suitable for pendants, earrings and occasional-wear rings rather than heavy-impact jewellery. The cabochon finish presents a smooth, domed surface without faceted edges, which highlights the stone's pleochroism, the ability to show different colours when viewed from different angles, typically blue, violet and burgundy in natural tanzanite. The listing indicates these are semi-precious gemstones intended for jewellery making, with the colour saturation and clarity grading dependent on the individual selection within each lot.

The material is natural tanzanite, a calcium aluminium silicate in the epidote group, with the chemical formula Ca2Al3(SiO4)(Si2O7)O(OH). The blue colouration arises from vanadium trace elements within the crystal lattice. Standard cabochon cutting for tanzanite follows a domed profile with a flat base, typical height-to-diameter ratios range from 1:3 to 1:5 depending on the intended setting. The mixed shapes suggest water-cut or freehand silhouette cutting rather than calibrated production. Typical clarity grades for cabochon-grade tanzanite range from lightly included to moderately included, as eye-clean material is usually reserved for faceted stones. The Jaipur cutting tradition typically employs aluminium oxide or diamond abrasives in a multi-stage tumbling and polishing process.

Jewellery manufacturers and independent designers purchase these cabochons for sterling silver and gold mountings, particularly in bohemian and artisan collections where organic shapes are valued. The irregular shapes suit wire-wrap settings and bezel cups, while rounds and ovals work with standard pre-made mounts. Buyers should confirm the exact size range, minimum order quantity and whether the stones have undergone any colour enhancement or heat treatment, as most tanzanite on the market is heat-treated to 500-600 degrees Celsius to intensify the blue component. Import documentation should specify whether the material is declared as rough, cut or worked stones for customs classification purposes.

H S R ENTERPRISES is based in Jaipur, Rajasthan, India, a location that places it within one of the world's most concentrated clusters of gemstone cutting, polishing and jewellery manufacturing. The company operates as a supplier, manufacturer, wholesaler and exporter, according to its own description, indicating a vertically integrated or multi-channel operation. The supplier tier is marked as imported, which in Indian B2B marketplace terminology typically denotes a seller whose primary business model involves importing rough or cut gemstones for further processing or direct resale. The trust tier is voyage, and the response rate shows 0.00 with zero average response hours, which suggests either a newly registered account, a dormant listing, or a business that processes enquiries through alternative channels rather than the platform messaging system.

The listing does not provide a company website, year of establishment, number of employees, annual revenue, specific factory details, or named international clients. No independent certifications such as ISO, RJC (Responsible Jewellery Council), or gemstone origin certificates are mentioned. Buyers should verify the company's physical premises, request samples before committing to bulk orders, and confirm whether H S R ENTERPRISES cuts material in-house or sources finished cabochons from third-party workshops in Jaipur's gemstone district. Direct communication via email or telephone, or a site visit, would provide more reliable due diligence than platform metrics alone.
