Lab-Grown Ruby Round Cabochon

This lab-grown round ruby cabochon is made with corundum using the flame fusion method. Each gemstone has a chemical make-up identical to those found in nature. It performs at the bench just as a natural gem would. The color produced is a deep red that makes a dependable, affordable and popular choice in place of natural ruby gemstones. Use the gemstone by itself for simple designs, or highlight the saturated color by pairing it with contrasting-color gemstones for a multicolor look. Ruby is the birthstone for July.
