Alexandrite the origin
- This excellent stone, which is green to blue-green in color and red to purple-red in incandescent light, is most commonly found in Russia. It has a moderately strong to high level of color saturation. The level of color intensity in too-light stones is not as high as in fine-quality gemstones.

What Cut
These are most frequently cut into mixed cuts, which have step-cut pavilions and brilliant-cut crowns. While brilliant cuts contain kite-shaped and triangulated facets with a gorgeous color change, vibrant colours, and extremely clear clarity, step cuts have concentric rows of parallel facets.
This genuine gem typically has an oval mixed cut. Cutting is challenging due to pleochroism. The strongest color shift across the crown of a natural alexandrite gemstone is arranged by cutters when they fashion it. In order for the completed stone to exhibit both the purple red and green pleochroic colours, it is imperative that the rough be arranged correctly.
