Peridot has a hardness of 6.5 to 7 on the Mohs scale, making it durable for everyday wear, but it can scratch or chip more easily than harder gemstones like diamonds.
Real peridot is usually eye-clean, with no visible inclusions. It has a distinctive olive-green color and a slight oily or greasy luster. A professional gemologist can confirm authenticity.
Peridot does not change color, but its appearance can vary slightly in different lighting conditions, sometimes looking more yellowish in artificial light and greener in natural light.
