Alexis: Our Alexis line of earrings features the beauty and style of full color-changing Chatham® Created Alexandrite gemstones. The Chatham Created Alexandrite exhibit very good (strong) color changing properties which range from a green-ish color in natural wavelength lighting (fluorescent lighting), and a purple-ish color in incandescent lighting.
Of all of the birthstones, Alexandrite is by far the rarest, hardest to find birth stone gem. They are far more rare than even Diamonds. Their rarity is also why Alexandrite is among the most expensive of all birth stone choices. Prices for gem-grade Alexandrite stones approaches that of even the best of Diamonds.
