As you know I am a gemologist who sells gemstones, this sapphire under the microscope presents one of the most beautiful inclusions shown by the untreated sapphires and rubies: perfect silk of rutile, with its needles perfectly shaped with tips like and of iridescent colors . All this beauty is incapable of supporting the heat that humans give to the corundum (sapphire and rubies) to improve their color. So when I saw on a scale of 50 magnifications its beautiful sharp points, I felt really good. It is very nice to see gems so beautiful not modified by men.
