Alexandrite is one of the most valuable gemstones in the world, celebrated for its unique ability to shift colors under different lighting. Often described as “green in daylight, red at night”, it has become a symbol of luxury, rarity, and mystical charm.
Understanding Alexandrite
Alexandrite is a rare type of chrysoberyl known for its optical phenomenon called pleochroism, meaning it can show different colors depending on the light source.
Under daylight, it appears vibrant green
Under warm or incandescent light, it shifts to red
This dramatic transformation makes
alexandrite one of the most sought-after gemstones on the planet.
Where Alexandrite Comes From
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:
Sri Lanka
Brazil
The Madagascar region
Tanzania
India
Zimbabwe
However, the original Russian stones remain the most prized.
The Rarity of Alexandrite
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.
How Alexandrite Changes Color
The gemstone absorbs and reflects different wavelengths of light depending on the source:

This strong color change is one of the most impressive among all gemstones.
