Laser Rod Alexandrite Facet Rough Lab Created Crystals

These are genuine, lab-created alexandrite facet rough sawn from decommissioned laser rods. Each stone is labelled with a letter and weight and can be purchased individually.We recently got our hands on a few decommissioned rods of alexandrite from lasers! These rods lived out a full career inside lasers as a crystalline lasing medium, but eventually they were pushed too far or had dust land in the wrong spot and the ends blew off, rendering them inoperable. Now they get to live out their retirement as gemstones! While they may have been designed for science they make amazing gems as well. They have a strong color change from blue-green to purple-pink and better yet often show flashes of both in mixed lighting when cut--the camera struggles to capture this, especially the green colors. On top of that they also show rich red fluorescence which affects their color, and the angle of lighting will also cause differences in color because this material is strongly trichroic.Alexandrite is th
