231,86 $

Jdiriya 005 is an Aubrite meteorite of only 35.6 grams, discovered by Brahim Ikken in 2018 in Morocco.

A new theory carried by a French scientific team talks about the possibility of a link between the Aubrites and the planet Mercury.

To date only 76 such meteorites have been classified.

It is a rare type of meteorite, difficult to find on the market.

The name Aubrites is linked to the fall of a meteorite in Aubres, France in 1836. They are composed mainly of orthopyroxene to enstatite.
