This high-quality lab-created ruby cabochon features unusual bubble-cut faceting on the high dome of the stone. The bubble cut displays circular, concave facets across the top of the stone that create the illusion of bubbles trapped inside. 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.

Lab-created ruby 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.

Rio round gemstones are calibrated for size and hand inspected to ensure maximum attractiveness.
