Quite surprising in person, we were very impressed to actually see an Iolite with a discernable 4-ray star.  Likely one of the species where asterism is rarest, we have never before had one of these.  Furthermore, with the large size and deep violet-blue color the star is actually fairly moderate in intensity, which is hugely impressive.  Very interesting and gemologically interesting, this is a rarity.
