Alexandrite is a type of chrysoberyl gemstone that is known for its color-changing properties. The presence of chromium in alexandrite is what causes it to exhibit different colors under different lighting conditions. Here's how to see chromium in Alexandrite:
1. Hold the alexandrite gemstone up to a source of light, such as a desk lamp or a window, and observe its color.
2. Change the lighting conditions by switching to a different light source, such as fluorescent or incandescent light.
3. Observe how the color of the alexandrite changes under the different lighting conditions. Alexandrite will typically appear green or bluish-green under daylight or fluorescent light and reddish or purplish-red under incandescent light.
4. Use a spectroscope to confirm the presence of chromium. Follow the same steps as described in the previous answer, observing the spectrum of colors produced by the alexandrite. The presence of chromium will cause a narrow band of red light to be visible in the spectrum.
5. If you do not have access to a spectroscope, you can also take your alexandrite to a professional gemologist who can confirm the presence of chromium using specialized equipment. They can also give you additional information on the quality and value of your alexandrite.
