This 33.79 gram slice of NWA 18452 is a finely prepared specimen of a Eucrite-breccia (Eucrite-br), part of the HED clan of achondrite meteorites widely associated with crustal material from differentiated asteroid bodies.

The specimen has been finished with a high mirror polish, giving the slice a sleek presentation that highlights the meteorite’s internal structure and makes it ideal for display or study.

Under ultraviolet light the meteorite shows clear fluorescence, and when the UV source is removed the specimen exhibits slight phosphorescence, continuing to glow briefly. This optical behavior is typically associated with mineral phases such as plagioclase within the meteorite and adds an interesting visual characteristic rarely highlighted in meteorite collections.

Northwest Africa 18452 is officially listed in the Meteoritical Bulletin as a Eucrite-breccia, recovered in Morocco with a total known mass of 5.49 kg.

For collectors seeking a polished and visually distinctive example of an asteroid-derived achondrite, this specimen offers both scientific significance and strong display appeal.
