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