Alexandrite

Alexandrite was discovered on April 17, 1834, in the emerald mines of the Ural Mountains in Russia, on the very day the future Tsar Alexander II came of age — earning the new gem his name. The Russian Imperial family adopted alexandrite as the national stone: its green daylight color and red incandescent light color matched the colors of the Russian military, making it instantly patriotic. The original Russian deposits were exhausted within decades, leaving Sri Lanka, Brazil, and East Africa as modern sources. Tiffany & Co. master gemologist George Frederick Kunz acquired most remaining Russian alexandrite in the 1890s, sparking a Western fashion for the gem in Belle Epoque jewelry. In 1987 a major find at the Hematita mine in Brazil reinvigorated supply, though high-quality alexandrite remains one of the rarest gemstones — finer than top-grade ruby in equivalent sizes.

Alexandrite represents transformation, dual perspective, and the ability to adapt. Its color-shifting nature — green in daylight (rich in blue-green wavelengths), red under incandescent light (rich in red-yellow wavelengths) — has made it the gem of those who navigate complex situations with grace. In Russian mystical tradition, alexandrite is associated with intuition and the balance between body and spirit. Vedic astrology assigns it to Mercury, the planet of intelligence and adaptability. Modern crystal healers consider it the gem of personal evolution: wear alexandrite when you are in transition between life chapters. The dual color symbolizes the integration of opposites — joy and sorrow, head and heart, day and night.

The Sauer Alexandrite, a 122-carat Brazilian crystal, is the largest gem-quality alexandrite ever found. The Smithsonian's National Gem Collection holds an exceptional 65.7-carat alexandrite. The Whitney Alexandrite, a 17.08-carat Russian-Ural specimen, sits at the Smithsonian. In 2016 a 21.41-carat Russian alexandrite sold at Sotheby's for $1.4 million per carat, breaking records. Tiffany's 1900s alexandrite jewelry collection — including pieces designed by Louis Comfort Tiffany — remains among the most collectible gems of the Belle Epoque era.

Alexandrite is hard (Mohs 8.5), suitable for daily wear in any setting. Treatments are uncommon — most alexandrite on the market is natural. Synthetic alexandrite (created since 1973) is chemically identical and substantially cheaper; reputable sellers always disclose it. Clean with warm water, mild dish soap, and a soft brush. Ultrasonic cleaners are generally safe for unfractured stones. Store separately from softer gems. To see the color change clearly, view alexandrite first under direct daylight, then under a candle or incandescent bulb.
