Beryl with Muscovite

Beryl with Muscovite from Laghman, Afghanistan, measuring 40 × 40 × 40 mm and weighing 91 grams. The specimen shows pale blue-green Beryl associated with layered mica. The contrast between those mineral forms is an immediate part of the specimen's appeal, giving a compact piece several distinct surfaces and shapes to explore.

Beryl is a beryllium aluminium silicate, while Muscovite is a potassium-rich mica with a sheet-like structure. The two minerals therefore provide a clear comparison between different silicate architectures. Beryl is familiar through its gem varieties, but a natural association with mica invites a broader geological reading, drawing attention to the minerals together rather than treating the Beryl only as gem material.

Laghman is the locality supplied for the specimen. The Afghan source adds a geographical focus to the Beryl-and-mica association. The near-equal overall dimensions give the piece a compact, three-dimensional character, and the photographs help convey how the Beryl and Muscovite relate visually within that small volume. The specimen comes from the David Vince Collection. Its appeal lies in the association and the opportunity to examine two contrasting silicate minerals at a convenient cabinet scale. The recorded Afghan locality and collection provenance complete that account, giving a naturally attractive mineral combination a clear identity to accompany it into its next collection.
