Spoiler alert. Staff favorite. Yes, that is a star in the center of this purple cabochon cut Sapphire. A small percentage of sapphires actually exhibit this star formation. A star this defined is beyond rare. Warm 18kt yellow gold and diamonds provide the backdrop for this piece of art. Vivid Alexandrite's right, left, top and bottom add never ending interest. The size, scale and elements here are jewelry perfection.
