Lot 1226
Large, Heavy 6.2 Pound Meteorite Sphere. Large etched iron-nickel meteorite spheres are highly sought after by both meteorite collectors and also collectors of mineral spheres. This 3½" diameter 6.2 pound Campo del Cielo sphere has a lovely widmanstatten pattern from the etching, as well as darker areas of graphite and troilite inclusions as found in this meteorite. The interesting-looking widmanstatten pattern results from two different alloys of nickel which have separated from each other by the asteroid core where this meteorite originated form cooling very slowly over several million years. Campo del Cielo meteorites fell 3,000-5,000 years ago in Chaco, Argentina. They are extremely difficult to cut because of the many silicate and graphite inclusions which break the cutting lathes.; large spheres are rare because more than 70% of the original meteorite is lost in the cutting process. the meteorite from which this sphere was produced weighed more than 20 pounds before it was cut. Add $30 for domestic shipping.
Estimated Value $1,300 - 1,500.
