Stony Meteorwrong - Convincing H5 or H6 Imposter Stone

$19.99

While searching for meteorites over the last two decades, nomads and  professional meteorite-hunters have recovered tens of thousands of meteorites of various types.  Many terrestrial rocks will mimic the appearance of a meteorite, so these "meteorwrongs" are often mixed in by accident with large bulk shipments as they hit the wholesale market.  Occasionally one of these imposter meteorites will find itself in the hands of a dealer who cuts it open to reveal it's true nature. 

This piece has all of the right criteria to be a meteorite - fusion crust,heavy for it's size, strong attraction to a magnet, and a hint of orientation.  I guessed this stone was an H5 or H6 chondrite, based on the  appearance of the specimen - it looked just like hundreds of such NWA chondrites I had cut over the years.

When I sliced a discrete window onto a corner of the stone, the inner matrix was all wrong - no metal flakes or inclusions, and no chondrules.  To my disappointment, I had to admit that this stone is a meteorwrong and that I wouldn't be making a profit on it.  Apparently the crust was actually a wind polished layer of desert varnish - an outer layer of terrestrial minerals deposited by thousands of years of exposure to the desert winds. 

However, not all is lost, because this stone would make a great display or outreach prop.  It is a tool for showing how normal Earth rocks can resemble a meteorite and fool an experienced eye.   This specimen is more than likely made of magnetite or some similar Earth mineral. 

This specimen weighs a substantial 265 grams, and is the size of a billiard ball.  Refer to the photos.  The black centimeter cube is shown for scale and is not included.
