Although unsigned, extensive research reveals that these are by Robert. The ornate metal work beautifully showcases the colorful unfoiled rhinestones. These pins also have hooks at the bottom and may have stated out life as a chatelaine, with a chain connecting the two.
The rhinestones are in shades of purple, green, and pink. There is a faux pearl at the top. Overall condition is excellent, I only see a few fleabites on some of the stones.
They measure 1.75 x 1.5 inches.
