It is also known as thebirthstonefor the month of June, and is related to thezodiac signof Gemini.Whether extracted from nature or createdin a lab, alexandrite engagement rings are a quick change artist, often noted as the ??emerald by day, ruby by night?¨¤ gemstone. When this gemstone was first discovered in Russia in 1834, it was mistaken for an emerald. It wasn?£¤t until the light changed that the miners realized they had discovered an entirely new gemstone, and it was given the name ??alexandrite?¨¤ for the Russian Tsar Alexander II. Glistening under sunlight, alexandrite stones appear a vivacious teal-green color, but when paired with artificial or incandescent light, a deep purple or magenta color takes over. With such duality, alexandrite engagement rings are perfect for the free spirited soul.
