WebAs birefringence increases, the colors repeat (see figure below), but get more and more pastel (washed out). To describe interference colors we must specify both a hue and an order (e.g., 2nd order red; see chart below). Minerals with low birefringence show only white, gray and black interference colors. WebBirefringence is a measure of a gem's double refraction. It serves as one of the principal ways gemologists can identify gems.
