The rarity of genuine alexandrite continues to fascinate gem enthusiasts worldwide. Few stones possess such a remarkable color change , transforming from vibrant under daylight to ruby under incandescent light . This phenomenon , known as the alexandrite phenomenon , is incredibly challenging to discover in substitute gems , making each individual alexandrite a true treasure and a coveted addition for any serious connoisseur. The small quantity further enhances its appeal and cost.
Revealing the Enigma: Understanding Natural Alexandrite Shade Change
The remarkable property of natural alexandrite to exhibit a dramatic color transformation – typically from green in daylight to red under incandescent light – is what makes it so highly valued. This display isn't just caused to ordinary pigments; it's a complex interaction of its unique crystal and its composition. The trace amounts of iron existing within the gemstone structure retain particular wavelengths of light. When the illumination type alters, the views at which these wavelengths are bounced vary, resulting in the perceived shade shift.
- Understanding this process highlights the rarity of truly natural alexandrite.
- Synthetic alexandrites often miss this consistent shade change or exhibit a less noticeable result.
- Genuine alexandrite possesses a near-perfect transition between green and red, giving it readily distinguishable to experienced experts.
Can True The Stone Grow Out of A Geographic Guide
The rarity of natural alexandrite makes locating its origins a fascinating exploration. Historically, Russia, specifically the Ural Mountains, was the primary area for alexandrite discovery in the 19th era . However, substantial occurrences have since been detected elsewhere. Today, the Brazilian region represents a important source of alexandrite, although the characteristics can vary from the Russian stone .

Identifying Natural Alexandrite: Expert Tips & Tricks
Distinguishing genuine alexandrite versus lab-created synthetics can be a challenge for even experienced gemologists . Below are some crucial indicators to look for . First, check the color change – natural alexandrite typically displays a dramatic shift from emerald green under natural light and ruby red, while simulated versions usually show a smaller change. Furthermore , earth-mined alexandrite usually exhibits slight inclusions – microscopic imperfections – that indicate evidence of a natural origin . Finally , its refractive nature reading of 1.69 - 1.70, along with density measurements, can give more information – though these types of testing demands specialized equipment .
