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.
Writeup from MB 110 :
Lahmada 048 27°24’20.78″N, 9°51’13.07″W
Saguia el Hamra, Western Sahara
Find: 2020 Sep 23
Classification: Ureilite
History: The meteorite was found by Brahim Elguirah. The meteorite was bought by Jean Redelsperger from Zaid Oualguirah in 2020.
Physical characteristics: A single dark brown stone
Petrography: (J. Gattacceca, CEREGE) Aggregate of blocky olivine grains (grain size 800 µm) with reduced margins. Metal, originally present along olivine rims, is almost entirely replaced by terrestrial weathering products. Contains a significant amount of carbon material, likely diamonds in view of the extreme difficulty to saw the rock.
Geochemistry: Olivine Fa21.9±0.4, CaO 0.36±0.02 wt%, CrO3 0.65±0.02, FeO/MnO = 53.4±7.9 (n=4). Olivine rim Fa5.1 (n=1).
Classification: Ureilite
Specimens: Type specimen at CEREGE. Mais mass with Jean Redelsperger.
Nwa 13512 is an Aubrite meteorite discovered in Morocco near Boudnib in 2019.
I this date only 72 meteorites of this type 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.

found together near Boudnib, Morocco were purchased by Mohammed Hmani in December 2019.
Petrography: (A. Irving, UWS and P. Carpenter, WUSL) The specimen has a mean grainsize of ~400 µm and is composed predominantly of equant grains of enstatite with subordinate sodic plagioclase and accessory altered Si-bearing kamacite, altered Cr-troilite and schreibersite.
Geochemistry: Enstatite (Fs0.2±0.0Wo0.6-0.7, N = 3), plagioclase (Ab91.4An2.6Or6.0; Ab76.4An21.4Or2.3; N = 2), kamacite (Si = 1.5 wt.%, Ni = 7.9 wt.%).
Classification: Aubrite.
Specimens: 20.5 g including one polished thin section at UWB; remainder with Mr. M. Hmani.

The Orcunama meteorite fell in the Philippines in 2011.
It has been classified chondrite type H3-4.
A single stone of 7800 g covered with a dark fusion crust was discovered.
On the clear and sunny morning of March 7, 2011, three farmers (Fredo Manzano, Edgar Francisco Senior and Enrico Camacho Junior) in Orconuma, Bongabonga, Philippines were clearing their field when they were startled by six consecutive loud explosions. The sound of the explosions seemed to last for half a minute. At first they thought it was thunder because the ground was shaking. As they looked up to the sky, they saw a “burning red object with sparks coming out of it”, leaving a thick trail of smoke and making a characteristic hissing sound before it hit the ground. By their own admission, the farmers initially thought it was a bomb and considered that it might be “the end of the world.” They remember that the birds flew away immediately at the sound of the explosions. They went to look, and less than 10 meters away, they found a hole in the ground, surrounded by stirred up dirt and what looked like burnt grass. Inside the hole, about 1 m deep, they saw a stone object and, lacking tools, they used a piece of wood lying nearby and their bare hands to dig it up. Not knowing what this strange stone was, they started asking around, and showing the stone to the locals, but then they were afraid someone would try to take it from them. This fear led them to wrap it in a sealed plastic container before burying it underground for a year. They finally decided that no one would come looking for it, so they dug up the stone and stored it in Fredo Manzano’s closet for the next 8 years. In 2020, they were interviewed for a local TV newscast (later posted on YouTube with over 5 million views), and during the filming, the stone was visually examined by geologist Jocelyn Villanueva, who concluded that it might be a type of basaltic volcanic rock. The farmers, however, remained convinced that it could be a meteorite and hired Ramelle Baquil Ramirez to help them find a buyer. Subsequently in April 2021, with the assistance of an experienced tektite dealer (Carmelita Cepe), the stone was acquired jointly by John Higgins and Jasper Spencer.

Chwichiya 002 is an ordinary carbonaceous chondrite of type C3.00 ungrouped, it is the most primitive type that has ever been found in this date, it has not undergone any hydrated phase and no heating before its expulsion from the parent body.
This meteorite is perhaps one of the most important meteorites of all times, no doubt that the knowledge of our solar system will advance thanks to it.
It was discovered in the Western Sahara. A must for a collection!
