Import Cubic Zirconia — Buy in Bulk from Supplier in India

Cubic zirconia from Shri Chatanya Sales Agencies is a synthetic gemstone composed of zirconium dioxide, engineered to replicate the optical properties of diamond. The material has a refractive index of approximately 2.15 to 2.18 and a dispersion value of 0.058 to 0.066, which produces strong fire and brilliance. Available in standard sizes ranging from 1.0 mm to 10.0 mm in diameter, it is offered in round, princess, emerald, and cushion cuts, with color grades ranging from D (colorless) to J (light yellow). Surface finish is typically polished to a high luster, with no visible inclusions under 10x magnification.

The material is stabilized with yttrium or calcium oxide to maintain its cubic crystal structure at room temperature, a standard practice in industrial-grade CZ production. It is harder than most natural gemstones except diamond, with a Mohs hardness of 8 to 8.5, making it resistant to scratching in jewelry applications. While not chemically identical to diamond, its thermal conductivity is significantly lower, allowing simple thermal testers to distinguish it. The stones are typically free from radioactivity and heavy metal contamination, meeting ISO 11623 standards for non-toxic gemstone materials.

This cubic zirconia is primarily purchased by jewelry manufacturers in Europe, North America, and Southeast Asia for use in costume jewelry, bridal wear, and fashion accessories. Buyers often source it in bulk lots of 10,000 stones or more, packed in foam-lined plastic trays with individual compartments. Trade terms are typically FOB Kolkata, with lead times of 7 to 14 days after order confirmation. Packaging is designed for export, with moisture-resistant sealing and customs-compliant labeling. Buyers should request a certificate of composition and a batch-specific refractive index report before final purchase.
