Black agate has a microscopic crystalline structure that allows light to be reflected and refracted in different ways, creating a range of colors within the stone.

Under strong light, black agate may ear to have a blue, red, or brown tint. This color change is due to the presence of impurities or mineral inclusions within the stone. For example, if the black agate contains iron oxide, it may ear red or brown in color. If it contains titanium, it may ear blue or even green. The colors that are visible within the stone depend on the type and amount of impurities present.
