Handmade Heart Pierced Clip Back Earrings + Chip Bead Sweater Clip Chain Set Southwestern.
Silver tone metal with turquoise color, orange, blue, red stones. It looks very 50s-60s to me, but if they are, the earring backs have probably been changed out for "modern" backs.
These chips may be real stones, but I am not representing them, nor pricing, as such.
