Alexandrite, a unique and captivating gemstone, has fascinated gem enthusiasts and collectors for centuries. Named after Tsar Alexander II of Russia, where it was first discovered, its distinct characteristic is its ability to change colors under different lighting conditions. In daylight, the gem often appears green, while under incandescent light, it takes on a reddish hue.
History and Discovery of Alexandrite
The tale of Alexandrite’s discovery is closely tied to Russian history. The gemstone was first unearthed in the Ural Mountains of Russia in the early 1830s. It was named in honor of Tsar Alexander II, and its unique color-changing property made it immensely popular in the Russian royal court. The stone’s colors, green and red, closely matched the national military colors of Russia, further deepening its significance.
Over the years, as the initial deposits in Russia started to deplete, new sources were discovered in other parts of the world. Countries like Brazil, Sri Lanka, and Madagascar have since become notable producers of this enthralling gemstone. Despite its global presence, the allure and prestige associated with Alexandrite’s Russian origins persist.

Maintenance Tips
- Cleaning: Use warm soapy water and a soft brush to gently clean your Alexandrite jewelry. Rinse thoroughly and dry with a soft, lint-free cloth.

Science Behind Alexandrite’s Color Change
Alexandrite’s most captivating feature is undoubtedly its ability to change color under different lighting conditions. But what causes this remarkable phenomenon? Delving into the science behind it reveals a combination of mineral composition and light interactions.
Chemical Composition
The foundation of Alexandrite’s color-changing capability lies in its chemical structure. Chromium ions are responsible for the color of the gem. Depending on the concentration and presence of these ions, the gem can display varying shades of green and red.
Light Absorption and Transmission
When light passes through Alexandrite, different wavelengths of light are absorbed and transmitted by the gem. Daylight, which is richer in blue and green wavelengths, makes the stone appear green. Conversely, incandescent light, which is richer in red wavelengths, will make the gem appear red.
Selective Absorption
Alexandrite’s unique crystal structure allows it to absorb specific wavelengths of light while reflecting others. The balance between the absorbed and reflected light determines the color perceived by the observer. For Alexandrite, the strong absorption bands lie in the yellow and blue regions of the spectrum, which is why green (a combination of blue and yellow) and red colors are predominantly reflected.
Impact of Cut and Orientation
The way Alexandrite is cut and oriented can also influence its color-change property. Facets and angles can either enhance or diminish the color change, making the gem cutter’s skill crucial in bringing out the best of Alexandrite’s unique feature.
In conclusion, Alexandrite’s mesmerizing ability to shift colors is a result of its unique chemical composition and the way it interacts with light. This interplay of science and nature gives birth to one of the most intriguing visual spectacles in the world of gemstones.
