Description

This high-quality round lab-created ruby cabochon features an innovative "Le Bouton" cut that offers a high-dome profile with a light-catching faceted surface. Use the stone by itself for simple designs, or pair 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.
