green/green gems

There are a variety of green and green-toned gemstones, including emerald, jade, peridot, demantoid garnet, diopside, and green tourmaline. Even if the colors are similar, highly transparent gemstones and opaque gemstones give a very different impression. The atmosphere also varies depending on the saturation, brightness, and cut.
