The 18-carat AAA-quality Alexandrite gemstone is a breathtaking example of one of the world's rarest and most sought-after gems. This natural color-changing gemstone, sourced from the renowned mines of Sri Lanka, is certified for authenticity and showcases an unparalleled blend of beauty, rarity, and exceptional craftsmanship. With its round brilliant cut, the gemstone is expertly faceted to maximize its brilliance and enhance its mesmerizing color transformation, making it a true masterpiece of nature. One of Alexandrite's most fascinating features is its remarkable ability to change color depending on the lighting conditions. Under natural daylight or fluorescent light, this exquisite gemstone exhibits a deep and vibrant greenish-blue to teal hue, exuding elegance and sophistication. However, under incandescent or candlelight, it undergoes a dramatic transformation, shifting into a captivating reddish-purple, magenta, or raspberry tone. This rare optical phenomenon, known as the Alexandrite Effect, is what makes this gemstone incredibly valuable and desirable.
