A little Space rock with a dramatic formation!
 
The life story of micrometeorite [NMM 3719] is described in the Project Stardust blog: https://www.facebook.com/photo?fbid=592510059562534&set=a.414001680746707
The fascinating rarity is a glassy (V-type, vitreous) micrometeorite with a nickel-iron bead in the front and a huge open gas vesicle from degassing of volatiles in the back. At the lower part are two smaller extremely shiny (pure nickel?) secondary/tertiary metal beads, the largest of the two surrounded by a narrow crystalline rim. In the thicker part of the glass, near the front is a still sealed gas vesicle. A raman spectroscopic analysis may reveal which volatile elements are trapped inside. 
 
The stone was found September 9, 2022, at Vallhalla Sports Arena, Oslo, Norway. Where Werner Herzog filmed his stardust hunt in the movie “Fireball” two years earlier.
