The beautiful forest green of bloodstone comes from iron, actinolite, and chlorite content, and the red is due to the presence of iron minerals. Sometimes the included iron and chlorite can mass in dense areas giving the appearance of moss, resulting in bloodstone occasionally being mistaken for moss agate. During the formation of jasper, many minerals layer, creating a wide variety of colors that hue, spot and blend or stipple together on the deep green background, (almost like a painter didn't fully clean their brush before adding another color to a canvas) and the effect is stunning! But because the red spotted green is not really "pure," this material is given yet another name, "fancy jasper."
