Description

Mimicking the royal blue color of natural sapphire, these marquise faceted imitation sapphires are composed of lab-created blue spinel. Designed as a sapphire simulant, they offer a rich, classic blue tone suitable for finished jewelry and custom metalsmithing work. These calibrated stones are generally safe for stone-in-place casting, making them a practical choice for production settings. Clean with warm, soapy water; ultrasonic and steam cleaning are generally safe. Please note that calibrated gemstone sizes may vary slightly by +/–0.10mm.
