We hope you’re having a gem of a weekend! Today’s Exhibit of the Day is a dazzling elbaite (variety: rubellite with quartz). In the late 1800s, gem-bearing pegmatites like this example were discovered in Southern California. What are pegmatites? They’re a special kind of rock formed by magma, characterized by large, occasionally enormous, interlocking crystals—sometimes of unusual minerals containing rare elements.

Large crystals typically mean that magma cooled slowly, allowing the crystals to grow for a long time. But pegmatites are rule-breakers—and are one of the most consistently puzzling aspects of geology. Special circumstances, particularly enrichment in H2O, allow them to solidify rapidly, sometimes in just a few days. Spot this beauty at the Museum’s Halls of Gems and Minerals!
