The Russian Alexandrite 0.42 ct is a rare gem of exceptional gemological significance, distinguished by its unique color-change properties and historical origin. As a member of the chrysoberyl family, this gemstone is renowned for exhibiting a remarkable russian alexandrite color change, shifting from a deep green under daylight to a purplish-red under incandescent light. This optical phenomenon, caused by the complex absorption spectrum of the mineral, is a defining characteristic of genuine russian alexandrite stones and serves as a key indicator of authenticity.
Sourced from historically significant deposits in the Ural Mountains, this alexandrite russian exemplifies the classic qualities for which early collectors prized Russian gems. The 0.42 ct weight allows the stone to showcase its precise cut, clarity, and saturation, enhancing the dramatic visual effect of the alexandrite stone’s color transition. Under professional gemological examination, the gem demonstrates high transparency, a well-balanced facet arrangement, and an absence of inclusions that interfere with its color-change properties.
The chemical composition of the russian alexandrite stone, primarily beryllium aluminum oxide with trace chromium impurities, is responsible for its extraordinary optical behavior. This intricate interplay of light and chromium concentration distinguishes Russian specimens from Alexandrite stones originating in other regions. As a result, the russian alexandrite remains highly valued among collectors, gemologists, and connoisseurs for both its scientific interest and aesthetic appeal.
Beyond its physical properties, the alexandrite stone carries significant gemological prestige. Its rarity, combined with the exceptional stability of its russian alexandrite color change, ensures that each specimen represents a unique example of natural crystallography and mineral chemistry. The 0.42 ct gem highlights not only the technical mastery of faceting but also the natural brilliance and intensity intrinsic to russian alexandrite stones, making it a distinguished addition to any serious collection or scientific reference.
