specimen number:
2063654

location:
Magnet Cove, Hot Spring Co., Arkansas, USA

description:
Classic thumbnail specimen for this famous locality, a twinned grouping of semi lustrous well-formed crystals of rutile without matrix. In good condition.

The Magnet Cove complex in Arkansas is a unique Cretaceous alkaline ring structure formed by intense igneous intrusions, creating a geological basin famous for an astonishing variety of rare mineral species. Historically, the area gained renown among researchers and mineral collectors during the nineteenth century as a premier locality. Small-scale digging and surface collecting over the decades have yielded world-class specimens, most notably sharp, lustrous, and frequently twinned rutile crystals. These dark red to black geniculate and cyclic twin formations of rutile, often found in weathered clay pockets, remain prized treasures for collectors and museums worldwide.
