|The Duchess of Cornwall's Cosmos Clip Brooches (Examples)|
Both of her clips are the same design, with heart-shaped petals, a stem paved in round diamonds, and the largest round diamond sitting in the center of the petals, but one is set in yellow gold and one is set in white gold. The Cosmos clips come in three sizes (small, medium, large) and I believe Camilla’s clips are the large size, which would have 101 diamonds apiece. The clips shown as examples here are from the range that is currently for sale, and they can also be used as pendants on a chain, but The Duchess uses hers solely as brooches.
These have been a part of her personal collection (presumably) since at least 2005, when they appeared at Ascot. She usually wears them together on one shoulder, occasionally splitting them up on her lapels or wearing just one at a time.
