This gemstone is one of the most valuable gemstones in the world, known for its remarkable ability to transform hues under different lighting. Often described as “green in daylight, red at night”, it has become a symbol of luxury, rarity, and natural wonder.
About the Alexandrite Gem
Alexandrite is a precious variety of chrysoberyl known for its optical phenomenon called pleochroism, meaning it can show different colors depending on the light source.
Under daylight, it appears bluish-green
Under warm or incandescent light, it shifts to purplish-red
This dramatic transformation makes alexandrite one of the most valuable gemstones on the planet.
Historical Background of the Stone
alexandrite was first discovered in the Ural Mountains of Russia in 1830 and was named after Tsar Alexander II. Because its colors matched the Russian military colors—green and red—it quickly became a national favorite among aristocrats.
Today, it is mined in:
Ceylon
Brazil
Madagascar
Tanzania
India
Zimbabwe
However, the original Russian stones remain the most prized.
Why Is Alexandrite So Rare?
Alexandrite forms only when rare geological elements, including beryllium and chromium, occur together under perfect conditions—an extremely uncommon event.
Because of this, high-quality natural alexandrite can be more valuable than diamonds.
The Science Behind Its Color Shift
The gemstone absorbs and reflects different wavelengths of light depending on the source:
Daylight → Shows more blue/green tones
Warm light → Shows more red/purple tones
This strong color change is one of the most impressive among all gemstones.
