A manmade gemstone that resembles peridot in color is typically created using synthetic materials to mimic the appearance of natural peridot. Zircon, a natural gemstone, can also be treated or synthesized to achieve a similar green color to peridot. These synthetic or treated zircon gemstones can offer a more affordable alternative to natural peridot while still providing a vibrant green hue. However, it's important to note that synthetic gemstones, including synthetic peridot or zircon, may not possess the same chemical composition or geological characteristics as their natural counterparts.
