This lab-grown star sapphire cabochon is made with corundum and offers an intense blue color. Each stone has a chemical make-up identical to those found in nature. It performs at the bench just as a natural stone would. Unlike natural sapphires, however, this stone is heat-resistant and can be successfully cast in place. For a variety of designs, this stone is a popular, affordable and reliable choice in place of natural sapphire. Sapphire is the birthstone for September.
