Alexandrite Sharp Briolette 3.6ct

This is a lab grown laser alexandrite laser faceted in a custom sharp briolette.  It weighs in at 3.6ct

This is a real lab grown alexandrite (not one of the many simulants) which was faceted from a laser crystal top.  This material is trichroic (meaning it shows three different colors depending on the direction you look through the stone, aligned with the faces of the cube), color changes under different lights and has strong red fluorescence--it basically looks a bit different every time you look at it.
