The plastic bar pin looks like apple juice bakelite but may not be. It has raised enameled flowers and a C-clasp on the back. It measures 2 5/8" by 3/8".
The yellow and silver tone dress/fur clip measures 1 1/2" by 1". 
The small cameo measures 5/8" by 5/8" and has a C-clasp on the reverse. The two-toned cameo is attached with prongs to a gold toned filigreed backing.
All three are in fine condition and will come in the small vintage embossed box in which they were found at an estate sale.
Please study the photos to fully appreciate the good condition of these 3 vintage pieces of costume jewelry.
These will be packed with care and shipped within 3 business days if not sooner.
