Alexandrite is a stunning, pleochroic color-changing gem ranging from blue/green to red/purple – and some in between! It also has a hardness of 8.5 which makes it great for everyday wear.
Our lab-crafted Alexandrites are grown using the Czochralski Pulled method which uses a tiny starter crystal that is dipped into a solution and very, very slowly pulled out. This process is so slow, that it only produces Alexandrite at a rate of 2mm/hour, but results in a lab-crafted gemstone that has the same optical properties and hardness as it’s mined counterpart.The brightness of our Alexandrite is RI 1.74-1.75, which is nearly identical to sapphire’s RI 1.76-1.77.
Stag & Finch has spent a lot of time and effort specifically optimizing our cutting designs to showcase Alexandrite’s optical
Lab Alexandrites offered by many other jewelers are mislabeled as lab-created when they are actually only a simulated Alexandrite. This means the crystal structure is not true to Alexandrite but an alternative that has somewhat similar properties. These alternatives could include lab-created color-change sapphire, color-changing Cubic Zirconia, or even specially created glass, among others.
