Lab-Grown Ruby Oval Faceted Gemstone Stone Size:12 x 10mm copper and most other non-ferrousMade from lab grown corundum, this oval gemstone displays a deep red color and is an economical alternative to natural ruby, the birthstone for July. Each gemstone has a chemical make up identical to those found in nature. It performs at the bench just as a natural gemstone would. 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.
