A massive, museum grade gem Sphalerite. They are dazzling stones with great color and dispersion - if they were just more durable they would be a sensation in jewelry. What is now uncommon here is the size of the stone and the fine cutting and great polish - remember these have a near adamantine luster in addition to the dispersion. A faceted gem of over 150 carats will be impressive in-hand, but one with the color and optical properties of Sphalerite will be doubly so. Some light veils and some typical fluid-type inclusions, but nothing distracting to the overall brilliance. The stone is nearly a full 1 1/2” in size.
