Description

Mimicking the royal blue color of natural sapphire, these emerald cut faceted imitation sapphires are composed of lab-created blue spinel. Offered in a range of calibrated sizes, they provide a consistent, affordable alternative to natural sapphire for finished jewelry, custom settings, and stone-in-place casting applications.

Features

  • Sapphire simulant — replicates the rich royal blue hue of natural sapphire
  • Composed of synthetic spinel — a durable lab-created material
  • Emerald cut faceted shape for elegant step-cut brilliance
  • Generally safe for stone-in-place casting, though some risk of damage may occur
  • Calibrated sizes for consistent fit in standard settings
  • Safe to clean with warm, soapy water; ultrasonic and steam cleaning are generally safe
