A 3.29 carat natural star ruby certified by GIA, displaying asterism — the optical phenomenon that produces a six-rayed star across the surface of the stone. GIA certifies the variety as Natural Star Ruby with no indications of heating, cut in a double cabochon style. The color is graded Purplish Red and transparency is Translucent, which is characteristic of star rubies as the rutile silk inclusions responsible for the star effect also reduce transparency.
