Footnote
The optical affect asterism can be seen in this star ruby with the application of a pointed light source (such as a hand torch), as microscopic inclusions within the stone reflect the light and produce a six-rayed star that moves with the light. Even in absence of applied light, this purple-ish red ruby exhibits a beautiful glow - almost reminiscent of the adularescence seen in moonstone - as rays of daylight enter the stone during daily wear.
