The rarity of genuine alexandrite continues to captivate gem collectors worldwide. Few stones possess such a remarkable color alteration, transforming from vibrant under daylight to ruby under incandescent glow. This display, known as the alexandrite characteristic, is incredibly difficult to locate in other gems , making each single alexandrite a true prize and a coveted possession for any serious collector . The small quantity further enhances its desirability and price .
Revealing the Puzzle: Grasping Natural Alexandrite Color Transformation
The remarkable ability of natural alexandrite to exhibit a dramatic shade shift – typically from green in daylight to red under incandescent glow – is what creates it so incredibly valued. This occurrence isn't just caused to simple colorants; it's a complex interaction of its unique mineral and its elemental. The trace amounts of vanadium existing within the corundum structure take in particular wavelengths of light. When the illumination source changes, the angles at which these wavelengths are shown differ, resulting in the noted color transition.
- Knowing this way emphasizes the scarcity of truly natural alexandrite.
- Synthetic alexandrites often fail this consistent color shift or exhibit a less striking outcome.
- Authentic alexandrite possesses a near-perfect transition between green and red, making it simply distinguishable to knowledgeable gemologists.
Where's True Alexandrite Be Found Out of A Overview
