Cartier’s original “Home Front” clip brooch is a rare wartime creation, designed to fuse patriotism with craftsmanship. At its center is a 9.60-carat, no-heat Ceylon sapphire, set in a bold mix of 14K yellow and pink gold. Patented by Cartier, the illusory design evokes the American flag reflected across a star-shaped form. Created during World War II, these brooches were more than adornment—they were symbols of support for the Allied effort, merging innovation with national pride.
