62,09 $

Lahmada 048 is an achondrite ureilite meteorite of only 59 grams discovered in the Western Sahara in a concentration area called Lahmada.

It was discovered on September 23, 2020 by Brahim Elguirah.

Lahmada 048 certainly contains diamonds in view of the difficulties to cut it.

The diamonds, which are rarely larger than a few micrometers in diameter, are probably the result of high-pressure shock waves produced by the collision of the parent body of the ureilites with other asteroids.
