The type specimen, 20.1g, is held at Cascadia.\u003c\/p\u003e\n\n\u003cp\u003eThe unbrecciated designation is the scientifically significant feature of this specimen. The Moon's surface has been heavily reworked by impacts across billions of years, and nearly all lunar material ejected to Earth arrives as regolith breccia, fragmented and compacted surface debris. A rock that escaped that processing preserves its primary igneous fabric from the original lava cooling event intact.

They formed during the earliest stage of lunar differentiation, when the global magma ocean was cooling and anorthitic plagioclase crystallized and floated to form the primordial highland crust. The olivine component places this lithology within the troctolitic suite, associated with the deep ancient highlands. The melt breccia texture records a subsequent chapter: one or more hypervelocity impacts energetic enough to partially melt the target rock and preserve fragments of the original troctolitic anorthosite within a shock-generated matrix. This stone encodes both the Moon's primordial crust and the violent processes that shaped it over billions of years.\u003c\/p\u003e\n\u003cp\u003eClassification was performed by J. Garcia at ADARA, Canary Islands. Petrographic analysis confirmed plagioclase averaging An97.9, reflecting the extreme anorthite enrichment characteristic of the lunar highland crust. FeO\/MnO ratios in olivine and pyroxene fall within the lunar range, consistent with Apollo highland samples and unambiguously distinct from terrestrial or Martian material. The shock stage is recorded as high. Weathering grade is moderate, consistent with a Northwest African find of recent recovery.\u003c\/p\u003e\n\u003ch2\u003eAcquisition\u003c\/h2\u003e\n\u003cp\u003eThis specimen is offered via private sale.

The FeO\/MnO ratios in olivine and pyroxene match the lunar value range established by Apollo samples. Plagioclase averaging An97.9 is characteristic of the lunar highland crust and essentially absent in terrestrial or Martian rocks.
