Mayan eccentric flints, 500 - 800 A.D. 

Eccentric flints, such as these, were sacred, high status offerings and evidence of the skill and technology of the Mayan workshops. A tapered base at the bottom may have been attached to a staff or scepter.

🛸👽 Today’s #macromonday shot was taken at the Munich Gem Shows, where I took a closer look at this kickass Seymchan Nickel-Iron Meteorite sphere!

The macro shows a unique structure that can only form in meteoritic metal: Widmanstätten patterns, aka Thomson figures. This structure forms due to 2 alloys within the nickel-iron material, kamacite and taenite—as the meteor (often an asteroid fragment) is flying through space, it cools slowly, and the 2 alloys differentiate and form distinct crystals.

When the meteor impacts with earth (becoming a meteorite), it is cut and treated with acid. The acid etches the meteorite and reveals its interior lattice structure, and these fine patterns of crystallization we call Widmanstätten patterns. A super cool formation that teaches us more about meteorites and the universe around us!
