The value of genuine alexandrite continues to fascinate gem aficionados worldwide. Few minerals possess such a striking color change , transforming from green under daylight to red under incandescent glow. This phenomenon , known as the alexandrite effect , is incredibly challenging to discover in substitute stones, making each specific alexandrite a true masterpiece and a coveted acquisition for any serious connoisseur. The limited supply further amplifies its allure and price .
Revealing the Puzzle: Grasping Natural Alexandrite Color Shift
The remarkable property of natural alexandrite to exhibit a dramatic shade transformation – typically from green in daylight to red under incandescent light – is what makes it so extremely valued. This occurrence isn't just attributed to ordinary dyes; it's a complex interaction of its unique crystal and its chemical. The trace amounts of chromium found within the gemstone structure take in certain wavelengths of illumination. When the illumination source changes, the views at which these wavelengths are reflected vary, resulting in the noted hue shift.
- Knowing this method demonstrates the scarcity of truly natural alexandrite.
- Lab-grown alexandrites often miss this consistent shade transformation or exhibit a less striking outcome.
- True alexandrite possesses a near-perfect evolution between green and red, allowing it simply identifiable to skilled gemologists.

Identifying Natural Alexandrite: Expert Tips & Tricks
Distinguishing real alexandrite from lab-created duplicates can be difficult for many experienced gemologists . Consider several crucial characteristics to look for . First, check the spectral change – natural alexandrite typically displays significant shift website between emerald green in sunlight and ruby red, while lab-grown versions frequently show a less change. Additionally , untreated alexandrite often exhibits slight inclusions – microscopic imperfections – that serve as proof of its natural source . Lastly , a refractive index reading of 1.69 - 1.70, along with weight measurements, can provide more information – though such testing requires specialized equipment .
