The College of Science weekly video series, Mineral Monday, explores the many minerals, fossils and historical objects on display at the W.M. Keck Earth Science and Mineral Engineering Museum, as told by curator Garrett Barmore. This week, Garrett brings out two staurolite crystals and explains their unique cross formation.

While they look like they may have ben carved to form a perfect cross, the twinned staurolite crystals form this way naturally.

Staurolite crystals can come un-twinned, and look more like a standard crystal without the unique cross formation you see here.
