This meteorite is a large, visually striking individual stone recovered from Niger in 2024, representing one of the 57 officially approved L5 melt breccia meteorites.\u003c\/p\u003e\u003cp\u003eThis 22.5 kg specimen exhibits the distinctive characteristics of melt breccias, where fragments of chondritic material are bound within a dark, glassy melt matrix. Visible metallic inclusions of kamacite and taenite, along with sulfides such as troilite and accessory chromite, enhance both the scientific and display appeal of this meteorite. Macroscopic flow-like structures in the melt and brecciation within clasts create visually dynamic textures that are highly prized by collectors.\u003c\/p\u003e\u003ch2\u003eOfficial Classification\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eName:\u003c\/strong\u003e Northwest Africa 17273 (NWA 17273)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry:\u003c\/strong\u003e Niger\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYear Found:\u003c\/strong\u003e 2024\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClassification:\u003c\/strong\u003e Ordinary Chondrite (L5 Melt Breccia)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal Known Weight:\u003c\/strong\u003e 22.5 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePieces:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOfficial Publication:\u003c\/strong\u003e Meteoritical Bulletin 114\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClassifier:\u003c\/strong\u003e J.T.
