Alexandrite is a fascinating and rare variety of the mineral chrysoberyl, celebrated chiefly for its remarkable color-change effect, known as the alexandrite effect. This gemstone shifts colors depending on the lighting—often showing greenish hues in daylight and reddish or purplish tones under incandescent light. The specimen described is a 0.33-carat alexandrite displaying green, red, and brown hues, attesting to its complex color profile. Such color change sapphires are sought after by connoisseurs for their rarity and visual intrigue. The International Gemological Institute (IGI) is one of the respected bodies that assess and certify gemstones to authenticate their properties. Alexandrite’s color change arises from trace amounts of chromium within the crystal lattice. It was first discovered in Russia in the 19th century and remains one of the most valuable and mysterious gems thanks to this characteristic optical quality.
