The preciousness of real alexandrite continues to captivate gem aficionados worldwide. Few stones possess such a unique color shift , transforming from emerald under daylight to crimson under incandescent light . This phenomenon , known as the alexandrite phenomenon , is incredibly challenging to discover in other stones, making each specific alexandrite a true treasure and a coveted acquisition for any serious collector . The restricted quantity further enhances its allure and cost.
Revealing the Mystery: Understanding Genuine Alexandrite Shade Shift
The remarkable characteristic of natural alexandrite to exhibit a dramatic hue shift – typically from green in daylight to red under incandescent glow – is what creates it so incredibly valued. This occurrence isn't just due to simple pigments; it's a complex interaction of its unique crystal and its chemical. The trace amounts of chromium existing within the corundum structure absorb certain wavelengths of glow. When the illumination origin modifies, the views at which these wavelengths are reflected change, resulting in the perceived color shift.
- Knowing this process demonstrates the rarity of truly natural alexandrite.
- Lab-grown alexandrites often fail this consistent hue change or exhibit a less dramatic outcome.
- True alexandrite possesses a near-perfect evolution between green and red, giving it readily identifiable to experienced experts.
Where Does Genuine This Gem Originate Out of A Guide
The scarcity of natural alexandrite makes identifying its origins a fascinating undertaking . Historically, Russia, specifically the Ural Mountains, was the primary area for alexandrite discovery in the 19th century . However, significant occurrences have since been detected elsewhere. Today, Brazil represents a important producer of alexandrite, although the characteristics can fluctuate from the Russian stone . Other smaller providing regions include Sri Lanka , Eastern Africa (primarily Kenya and Tanzania), and Southern Africa , each offering alexandrite with particular characteristics .

- Beauty: The visual allure stays to captivate.
Identifying Natural Alexandrite: Expert Tips & Tricks
Distinguishing natural alexandrite versus lab-created duplicates can be a challenge for even experienced gemologists . Consider a few key indicators to assess. First, check the color change – natural alexandrite typically displays a dramatic shift to emerald green under natural light and ruby red, whereas simulated versions frequently show a weaker change. Additionally , natural alexandrite often exhibits minor inclusions – tiny flaws – that indicate evidence of its natural beginning. Finally , a refractive index reading of 1.69 - 1.70, along with weight measurements, can give additional information – though these types of testing necessitates specialized equipment .
