About this subject

Alexandrite is a variety of chrysoberyl discovered in 1830 in the Ural Mountains of Russia, named after Tsar Alexander II. Its most notable feature is the color change effect: under natural or fluorescent light, the gem appears green to bluish-green, while under incandescent light or candlelight, it turns red or violet-red. This phenomenon occurs due to chromium impurities in its crystal structure, which absorb and transmit different wavelengths.

The rarity of high-quality alexandrite is extreme, especially those exhibiting a pronounced color change and vivid hues. Significant deposits exist in Brazil, Sri Lanka, Tanzania, and India, but historic Russian gems are most prized. Rings like this combine the gemstone with sophisticated settings, often in platinum or white gold, enhancing its brilliance.

The setting of a French chateau evokes the luxury of 19th-century European nobility, a time when alexandrite became popular among royalty. This piece is not only jewelry but a testament to mineralogy history and gem trade. Collectors seek these stones not only for beauty but also as investment, as top-quality specimens appreciate over time.
