From the Hope Diamond to the "Blue Flame," one of the world's largest and finest pieces of gem-quality lapis lazuli, Jeffrey Post, geologist and curator-in-charge of the National Gem and Mineral Collection at NMNH, will explore the findings behind what makes things blue, and the science that explains these rare and valuable natural wonders.

After the program, get a chance to engage with Jeffrey Post and get a closer look at some of the objects in the Gem and Mineral Collection. 

This program is presented as part of the Beyond the Exhibition: Objects of Wonder series, which offers opportunities to look more closely at some of the objects in the acclaimed Objects of Wonder exhibition at the National Museum of Natural History. 

The Objects of Wonder exhibition is located on the second floor of the National Museum of Natural History. Open to the public from 10 a.m. to 5:30 p.m. daily.
