Lab-Created Blue Spinel Oval Faceted Stones


This lab-created spinel offers an almost electric-blue color with an eye-clean clarity. The well-saturated color makes this stone popular for a variety of jewelry—even birthstone—designs and is an ideal alternative to more-costly precious gemstones.

Lab-created spinel presents a bright, clear color and is both economical and versatile. Each stone has a chemical make-up identical to those found in nature. It performs at the bench just as a natural stone would. For a variety of designs, this spinel is a popular and affordable choice over more costly gemstones to get the color you want.

The oval cut is an even, symmetrical shape but elongated. The arrangement of its facets is similar to that of a round brilliant, designed to maximize light and color.
