Different Kinds Of Star Cut Cubic Zirconia Gems

These star cut cubic zirconia gems are precision-cut synthetic stones with a 57-facet star pattern designed to maximize light dispersion and fire. The material is zirconium dioxide with trace additives to enhance refractive index and clarity. Standard sizes range from 1.5mm to 10mm in diameter, with a consistent 1.8mm thickness for round stones. Each gem is faceted using computer-controlled machinery to ensure symmetry and optical uniformity.

The gems are manufactured without lead content and meet ISO 11449 standards for optical clarity and surface finish. Typical refractive index is 2.15 - 2.18, and dispersion is 0.058 - 0.060, comparable to diamond. Colors include clear, black, pink, blue, and green, achieved through dopant elements such as cobalt or chromium. The surface hardness is 8.5 on the Mohs scale, making them suitable for daily-wear jewelry applications.

These gems are primarily purchased by jewelry designers, costume jewelry manufacturers, and bridal accessory suppliers. Orders are typically placed in lot sizes of 100 to 10,000 pieces per color and size. Packaging is in sealed anti-tarnish pouches with foam inserts, grouped by size and shade. Delivery is commonly FOB Nanning or CIF port of destination, with lead times of 7 to 14 days after payment confirmation.
