The ornaments are attached to a pieced strip of worn, dark red velvet with a satin backing, of uncertain date. Eight are enameled in blue.
X-ray fluorescence analysis of the metal disks indicated they are made of mercury-gilded (fire-gilded) silver. The light and dark blue enameled areas contain silver (perhaps from the base) and small amounts of copper, zinc, and lead. The green areas contain the same elements, with a greater concentration of copper, which is probably responsible for the coloration in both the blue and green areas.
