Comment: Often color-changing sapphire with rays of green, purple and blue coming from a dense blue violet which one may find in a thunder cloud at dawn just before hell breaks loose. Some tiny inclusions can only be seen under the lens and then only to the trained eye. Good luster in various colors. See side image for other colors.
