A relatively young gemstone, Alexandrite was named after Czar Alexander II the day he came of age. Called the "stone of good omen", this crystal changes from flashing a blue-green hue in natural light to a red-violet in artificial. The extraordinary color changing properties make this a unique and sought after gem. Offered here are some one of a kind necklaces featuring the exquisitely beautiful Alexandrite gemstone, finely set in sterling silver.
