A Kaleidoscope of Butterflies Brooches

Six colorful butterfly brooches 2” wide blue/green glass butterfly with black back; 1” wide crystal glass butterfly with blue tipped wings and green tipped antennae, silver tone back; 1” gold tone filigree wings with pretty brown/gold glass stone body, gold tone back ; 1/4” gold tone butterfly, wings filled with what looks like tiny faux pearls but it’s so small, I’m not sure; 2 matching 1/3 cream colored matching enamel butterflies. Measurements are approximate. No brands. I can’t see any missing stones or damage. I can’t get the back open on the 1/4” butterfly. It looks like it should open and I may just be missing how to go about it. All other closures work. These are beautiful brooches, with a lot more shine and glitter than I could capture in the photos.
