Iron-NickelKalahari Desert, Namibia, AfricaFrom an old collection, this Gibeon slice boasts original fusion crust and is beautifully etched, displaying the specimen's highly desirable Widmanstätten pattern. It is also distinguished by an interesting band without Widmanstätten pattern indicating that the nickel alloys lacked separation in this section. Gibeon iron-nickel meteorites are in very high demand as they are hard to find and possess the most beautiful internal crystalline structure when cut and etched. This crystalline pattern does not exist in any rocks on Earth and only forms when the iron core of the meteor cools very slowly at no more than a few degrees Celsius per million years. Gibeon meteorites were found in the Kalahari Desert of Namibia, Africa from a fall occurring thousands of years ago. The present offering is an etched slice with fusion crust on all sides and a fine-grained Widmanstätten pattern of crystallization visible on both sides. Weighing approximately 219 grams (0.48 lbs) and measuring 5 x 4 in
