What is Alexandrite?
Alexandrite is one of the rarest gemstones in the world and the official birthstone for June. It also holds the title of Anniversary stone for the 55th year of marriage, and is sometimes called a “Friday’s stone” — the stone of “Friday’s Child.” The gem was first discovered in 1830 in emerald mines near the Tokovaya River in Russia’s Ural Mountains, on the birthday of Prince Alexander II — which is how it got its name.
While Alexandrite first gained recognition in the jewelry salons of St. Petersburg and Paris, it was America’s Tiffany & Co. that brought it global fame. George Kunz, Tiffany’s master gem buyer, fell in love with the stone and traveled to Russia specifically to source it.
The Science Behind Alexandrite’s Color Change
Alexandrite belongs to the chrysoberyl mineral family. What sets it apart from other chrysoberyl varieties, like cat’s eye, is the presence of chromium alongside iron and titanium as a major impurity — a combination that gives the stone its signature yellowish-green to brownish-green base color.
The most prized shades are described as “emerald grass, splendid, or elegant” in green, and “ruby, columbine, garnet, and raspberry” in red. The defining trait, however, is pleochroism — Alexandrite’s ability to shift color depending on the light source. In daylight, it appears green to bluish-green; under candlelight or artificial light rich in red rays, it turns red or reddish, much like watching a traffic light change. The more distinct and dramatic this shift, the more valuable the stone.
Alexandrite is typically found in small sizes — stones over five carats are considered large and command significantly higher prices. It’s also remarkably durable, ranking harder than diamond on the Mohs scale, which adds to its reputation as one of the rarest and most technically demanding gemstones in the world.
Alexandrite in Astrology
Alexandrite’s color-changing nature has made it significant in astrological practice as well as jewelry. In Vedic astrology, Alexandrite is associated with the planet Mercury (Budh), and is believed to help with clarity, decision-making, creativity, and emotional balance. It’s often recommended for those navigating major life or career changes, or seeking better focus and communication.
Astrologically, Alexandrite is considered especially beneficial for Gemini and Virgo, both Mercury-ruled signs, though it’s often worn as a more universal stone for balance and transformation. As with any gemstone chosen for astrological purposes, it’s worth confirming through a proper free gemstone recommendation or astrology consultancy before wearing it, since Mercury’s placement in your own birth chart determines whether the stone will work in your favor.
