The Unique Chameleon-like Quality of Alexandrite: An Explanation
In the captivating realm of gemstones, few are as mesmerising as Alexandrite. Discovered in the Russian Ural Mountains in 1834, this rare gemstone has since captured the hearts of jewelers and collectors alike.
Alexandrite's most prized feature is its remarkable colour change, a phenomenon that sets it apart from other gemstones. Under natural daylight, the gemstone appears bluish-green or green, while under incandescent or candlelight, it transforms into plum red to reddish hues, mirroring the colours of the national military of Imperial Russia, for which it was named the official stone of the Tsardom of Russia. This colour change is caused by the complex interaction between Alexandrite's crystal structure and the light source's spectral composition, with different light sources emitting different wavelengths, leading to distinct colours under varying lighting conditions.
The rarity of Alexandrite is partly due to its unique source locations, notably Brazil and Russia, and the limited availability of high-quality stones that show strong colour change. Due to its scarcity and distinctive qualities, many gemologists and jewelers have limited experience recognising natural Alexandrite, sometimes mistaking it for synthetic or other stones. Gems over 1 carat with certification from reputable authorities like the Gemological Institute of America (GIA) tend to have higher value due to guaranteed authenticity and quality.
Alexandrite's value is closely tied to the strength and quality of its colour change, with stones exhibiting a 90-100% colour change being the most valuable. The size (carat weight), clarity, and origin also affect value, but the colour change takes precedence. Certification from trusted gemological labs and proprietary authenticity guarantees further enhance the stone’s market value by assuring buyers of its natural origin and quality.
In addition to its colour change, Alexandrite also exhibits strong pleochroism, appearing different colours from different directions. The pleochroic colours are green, orange, and purple-red. Despite its rarity, the value of Alexandrite is significantly affected by the quality of its colour change. Synthetic colour change sapphire is a common simulant for Alexandrite on the market.
The world's largest faceted Alexandrite, weighing 65.7 carats, hails from Sri Lanka. The finest quality Alexandrites are traditionally from the original deposits in Russia, mined out in the 19th century. Today, Alexandrite is also mined in Brazil, Myanmar, Tanzania, India, Madagascar, and Sri Lanka.
In conclusion, the unique colour change property primarily drives Alexandrite’s rarity and value, and this phenomenon is a sophisticated interaction between the gem and varying light wavelengths. Authenticity and certification alongside these factors further determine its market worth. The allure of Alexandrite lies not only in its captivating colour change but also in its rarity and historical significance, making it one of the world's most desirable gemstones.
