ELEGANT! In fact, one seldom sees such finely formed specimens in a miniature size from this mine. Most are bigger and bulkier. This features a central, curving, doubly-terminated, spinel twin of copper, measuring 5.1 cm in length. This graceful core crystal is offset at right angles by smaller parallel-growth spinel twin crystals. The crystals have a patina colored a rich brownish-red (untouched by acidizing) which was so classic for these pieces. Aesthetic!
