Description

Mimicking the royal blue color of natural sapphire, this heart-shaped faceted stone is composed of lab-created blue spinel. Offered as a sapphire simulant, it delivers rich, saturated color at an accessible price point—making it an excellent choice for finished jewelry, custom designs, and resale applications.

This stone is generally safe for stone-in-place casting, though some risk of damage may occur depending on casting conditions. Clean with warm, soapy water. Use of ultrasonic and steam cleaners is usually safe. Calibrated gemstone sizes may vary slightly +/– 0.10mm.
