The Denver Art Museum had an exhibit called Brilliant: Cartier in the 20th Century which I was lucky enough to see in its last few days. There were many beautiful tiaras at the Cartier exhibit. While I loved the early tiaras for their ornate garland style, this beautiful aquamarine is also timeless. The Hesketh Aquamarine Tiara Museum Monday is an every other week series about museum news, objects, and reviews.
