Join us as we welcome Dr. Jeffrey E. Post, curator-in-charge of the National Gem Collection, as he presents a beautifully illustrated talk on the Smithsonian Institution’s rare and magnificent gems.

The collection includes the notorious Hope Diamond; the exceptional 423-carat Logan sapphire; and the Carmen Lúcia ruby, one of the largest and finest examples in the world. It is also known for its historic pieces, including the Marie Antoinette earrings, the Blue Heart diamond, the Marie Louise Necklace and the Maximilian emerald. Post will explore the rich, fascinating stories behind some of the famous gems in the collection.
