This unique and captivating variety of chryso - beryl, renowned for its striking ability to change colour, was first discovered in the Ural Mountains of Russia 1830 and named after Alexander II, the ruling Czar at the time. The gemstone displays green hues in daylight and reddish in incandescent lights, mirroring the colours of Imperial Russia’s flag, quickly became popular amongst nobility, embodying a symbol of heritage and aristocracy. Across cultures, al - exandrite came to represent harmony between opposites, represented by its rare ability to shift between two distinct hues and adopted as one of June’s modern birthstones. The remarkable colour shift of alexandrites is caused by the mineral’s intricate interaction with light. These unusual gemstones have been prized for their dual nature and rarity. Fine alexandrites are exceptionally scarce, typically discovered only in small sizes, large, clean crystals are ex - tremely uncommon. Even among those found, not all display the vivid and well-balanced colour change that defines the finest specimens, making top-quality stones with strong, distinct transitions between green and red extraordinarily rare and highly sought after. Russian mines were depleted in a 40-year span since their discovery, but today, alexandrite is found in select locations around the world, in- cluding Brazil, India, and Sri Lanka.
