What a lunar! It has been classified as an impact melt breccia with angular to sub-rounded mineral and lithic clasts set in a predominantly vitreous matrix composed of brown, flow-banded, vesicular, partly devitrified glass and fine-grained crystalline impact melt. Lithic clasts consist primarily of anorthitic plagioclase (some partially coverted to maskelynite) with smaller quantities of olivine, pigeonite, low-Ca pyroxene, sub-calcic augite, and Si-Na-Ca-Mg-rich glass; a variety of lithic clasts were observed to display poikilitic, granulitic, dendritic, porphyritic, or subophitic textures in thin section. Accessory phases present include kamacite, troilite, chromite (some containing Ti), and ilmenite – as per the Meteoritical Bulletin.

In his global travels spanning over two decades, Geoff Notkin amassed a truly world-class collection of meteorites, which we are pleased to present. These pieces are an assemblage of top-quality examples of stone and iron meteorites, pallasite, mesosiderites, impactites, and lunar and Martian specimens. Also represented are historic and rare meteorite types, which often come with the best stories.

Geoff has opened his vault and pulled some of his long-time favorites, meticulously hand-painting Notkin Collection (NC) numbers on some. Experienced collectors will spot famous meteorites among the lot, including rocks Geoff pulled from the ground himself from impact sites around the world. This is a spectacular opportunity for novice collectors as well, who would do well to pick up a Notkin Collection meteorite not likely to circulate the market in the future.

Each Notkin Collection piece is accompanied by a special identification card, signed by Geoff himself, that includes that meteorite’s unique NC number.
