The Spellbinding Science Behind Color-Changing Gemstones
You know what makes color-changing gemstones even more magical? The mesmerizing science that powers this amazing phenomenon.
The star of this chromatic magic show is pleochroism, an optical property that makes some crystals show different colors when viewed from different angles. This effect is a result of the way these crystals absorb light, causing the gemstone to change its color when seen from different perspectives.
But, that’s not the only trick up their sleeve! Some gems put on a different kind of show, thanks to the Alexandrite effect. Named after the Alexandrite gem, this effect causes color change depending on the light source rather than the viewing angle. This is why Alexandrite appears green under daylight or fluorescent light and turns a charming red under incandescent light.
All this color-shifting magic is the result of a complex dance between the gemstone’s crystal structure, the light it interacts with, and the human eye that perceives the color. It’s a fascinating display of nature’s craftsmanship, and to truly grasp it, we must understand the principles of optics and appreciate how nature can ingeniously manipulate materials to create such bewitching visual effects.
