NWA 15972 LL3 (estimated subtype 3.2) #8 – 5.4 g

144,61 $

NWA 15972 is a beautiful LL3 chondrite weighing just 317 grams.

The estimated subtype is LL3.2; as of now, there are only 21 meteorites of this type in the world.

Of the more than 80,000 meteorites recorded on Earth, this tiny number confirms the extreme rarity of this type of primitive rock.

LL3.2 chondrites are considered to be true “time capsules” of our early solar system.

This meteorite was analyzed at Cerege by Jérôme Gattacceca.
