Comment: Giant blue sapphire with the looks of a 6+ carat gem. Posh even for a gents ring. Only the lens reveals some mini inclusions and a structure of very finest needles giving it a fluid lively appearance - it seems to never be still but in motion as if a current runs through it. The color is of a rich violet sky blue (in times before smog was invented). Perfect Jyotish gem. Great value under 2.5k/carat in this size.
