This lab-created star sapphire oval cabochon offers the signature look of sapphire at an attractive price point. Set it in PMC+™ and PMC3™ designs; it will withstand the heat of firing. Star sapphire is created from lab-grown blue corundum and presents a distinctive six-ray star, easily visible under any light source, that is the result of the introduction of titanium into the growing process. The titanium forms inclusions in the forming mineral structure that, under intense heat and pressure, produce the appearance of the star. The star effect, known as “asterism,” tends to be more defined and easier to see in a created stone.
