Mesosiderite Meteorite Jewelry I NWA 4747 Meteorite in Sterling Silver Pendant

Top Meteorite

  • $ 220.00


 

On Offer: Beautiful Mesosiderite Meteorite Pendant set in Sterling Silver. This unique center piece shows off a bright extraterrestrial metal contrasting a dark igneous mafic stone. It comes from the transitional zones of a large differentiated asteroidal parent body where most of the asteroid's (or possibly even minor planet's) metals was heated and drawn down to the center by gravity to form an iron-nickel core. The mesosiderites are thought to represent mixing of the outer boundaries of the metal core with lighter rocky silicates to form a 50/50 (on average) mix of metal and stoney material. Hence the term "stoney-iron" that is often used to describe them as a group casually. This mesosiderite was discovered in the desserts of Morocco in 2001.
