Portuguese Cut Alexandrite Oval, 1.19 cts
Fine Portuguese style cutting with good proportions, no windowing, and excellent symmetry. The color change is strong and attractive in every kind of light. The stone is very slightly included in one spot near the girdle and this inclusion is very difficult to see without magnification. The daylight blue-greens of the stones from this deposit are the best.
