Ain Ben Tili 007 — 7.63 g Diogenite Half Stone COA included Offered here is an attractive 7.63 g half stone of Ain Ben Tili 007, an achondritic meteorite classified as a diogenite, belonging to the HED meteorite group. This specimen combines two particularly desirable features in a single piece: a substantial portion of the natural exterior has been preserved, while the broad cut face provides an excellent view into the meteorite's internal structure. A surface that changes with the light One of the most fascinating characteristics of this particular specimen cannot be fully captured in a single photograph. When the stone is slowly tilted under a light source, certain Ca-pyroxene crystal faces strongly reflect the incident light, producing bright, almost metallic-looking flashes across parts of the cut surface. The effect is highly dependent on the angle of illumination: crystals that appear relatively subdued under diffuse light can suddenly become intensely reflective when their cleavage or crystal surfaces are oriented correctly toward the light. This makes Ain Ben Tili 007 especially rewarding to examine in the hand. Rotating the specimen reveals details and reflections that a static photograph simply cannot reproduce. A differentiated asteroid rock Diogenites are fundamentally different from ordinary chondrites. They are achondritic, igneous rocks originating from a differentiated parent body and consist predominantly of pyroxene. Ain Ben Tili 007 therefore represents material that underwent geological differentiation and crystallisation on another body in the Solar System rather than preserving the primitive chondrules characteristic of ordinary chondrites. Diogenites belong to the HED clan — howardites, eucrites and diogenites — a remarkable family of differentiated meteorites. The HED parent body is widely associated with asteroid 4 Vesta, although scientifically it is more precise to describe Vesta as the strongly supported parent-body interpretation rather than to claim that the individual meteorite's launch location is known directly. An excellent display specimen At 7.63 grams, this is a substantial half stone rather than a tiny fragment. The cut face allows the internal mineralogy and texture to be examined directly, while the remaining natural exterior preserves the meteorite's original three-dimensional character. Under changing illumination, the reflective pyroxene crystal surfaces give the specimen an additional visual quality that is best appreciated in person. This combination of natural exterior, exposed interior, visible crystalline texture and strong reflections from individual crystal faces makes this a particularly attractive example for both a meteorite collection and display.
