These are one of two pairs of vintage enamel on ceramic traingle-shaped earrings I found on a recent trip to Kansas City, from the same collection. I think these would be especially great with a little black dress and gold pumps. But also with a well cut, sharply pressed white shirt. Or a navy suit. Or a purple tank. Or! Super chic, very late 70s, very right now.
The longest side of the triangle is 1.25". Clip backings. Great condition.
