The preciousness of real alexandrite continues to enchant gem aficionados worldwide. Few stones possess such a striking color alteration, transforming from green under daylight to ruby under incandescent glow. This phenomenon , known as the alexandrite characteristic, is incredibly challenging to find in other stones, making each individual alexandrite a true prize and a coveted possession for any serious fancier . The restricted availability further amplifies its allure and worth .
Unlocking the Enigma: Grasping Genuine Alexandrite Hue Shift
The remarkable ability of natural alexandrite to exhibit a dramatic shade change – typically from green in daylight to red under incandescent light – is what defines it so highly valued. This phenomenon isn't just caused to ordinary colorants; it's a complex interaction of its unique structure and its composition. The trace amounts of iron existing within the gemstone structure absorb certain wavelengths of illumination. When the light origin changes, the perspectives at which these wavelengths are shown change, resulting in the perceived shade shift.
- Knowing this process highlights the scarcity of truly natural alexandrite.
- Imitation alexandrites often fail this consistent hue transformation or exhibit a less dramatic effect.
- Authentic alexandrite exhibits a near-perfect transition between green and red, making it simply distinguishable to skilled experts.
Where's Genuine This Gem Come In A Geographic Exploration
The rarity of natural alexandrite makes pinpointing its origins a fascinating exploration. Historically, Russia, specifically the Ural Mountains, was the primary source for alexandrite discovery in the 19th era . However, considerable occurrences have since been uncovered elsewhere. Today, South America represents a important supplier of alexandrite, although the characteristics can vary from the Russian stone . Other minor producing regions include Sri Lanka , African countries (primarily Tanzania ), and Zimbawe, each yielding alexandrite with unique qualities .

Identifying Natural Alexandrite: Expert Tips & Tricks
Distinguishing genuine alexandrite from lab-created duplicates can be difficult for some experienced experts. Here's a few crucial characteristics to assess. First, check the hue shift – natural alexandrite typically displays a dramatic shift to emerald green under natural light and ruby red, while simulated versions frequently show a less change. Additionally , earth-mined alexandrite usually exhibits minor inclusions – microscopic click here flaws – that are proof of its natural beginning. Lastly , a refractive index reading of 1.69 - 1.70, along with weight measurements, can give additional information – though these testing necessitates specialized tools .
