Trinitite is a glass made during the first nuclear explosion called Trinity, in Alamogordo, New Mexico on July 16, 1945.
Trinitite is made from the vitrification of the desert sand linked to the different elements of the structure on which the bomb rested and the bomb itself. Recently, researchers discovered that a piece of red Trinitrite took the form of a quasicrystal.
First discovered in the laboratory in the 1980s, quasicrystals also occur in nature, notably in meteorites.
A total of 1600 kg, ranging in mass from << 1 to 35,000 g, and a single 83 kg individual completely covered with regmaglyptes, were found in the Kamil impact crater in Egypt. This 45 m diameter crater was discovered by an Italian-Egyptian geophysical team in February 2009 and February 2010. Approximately 800 kg of the total mass observed in the field (including the regmaglypted individual) was recovered.

NWA 14425is an enstatite chondrite meteorite, classified EH3.
This metal-rich meteorite is hard to find on the market.
Writeup from MB 111 :
Northwest Africa 14425 (NWA 14425)
(Northwest Africa)
Purchased: 2021 Feb
Classification: Enstatite chondrite (EH3)
History: Purchased by Jason Whitcomb in February 2021 from an Algerian dealer.
Petrography: (A. Irving, UWS and J. Boesenberg, BrownU) Mostly relatively small enstatite-forsterite-bearing chondrules (exhibiting a wide size variation, apparent diameter 380±410 µm, N = 24) are set in a fine grained matrix containing daubreelite, troilite, altered Si-bearing kamacite, perryite, schreibersite, oldhamite and albitic glass. Several chondrules contain relatively ferroan low-Ca pyroxene.
Geochemistry: Enstatite (Fs1.3±0.9Wo0.4±0.3, range Fs0.3-4.1Wo0.0-1.0, N = 19), forsterite (Fa0.3±0.1, range Fa0.3-0.4, N = 3), relatively ferroan low-Ca pyroxene (Fs13.4±3.8Wo3.0±1.1, range Fs11.4-19.1Wo4.2-1.9, N = 4).
Classification: Enstatite chondrite (EH3). The presence of relatively ferroan low-Ca pyroxene in addition to the dominant enstatite has been previously documented in EH3 chondrite Yamato 691.
Specimens: 24.83 g including one polished thin section at PSF; remainder with Mr. J. Whitcomb.
